Logitech Mobi Fold review

The Logitech Mobi Fold is, without question, the weirdest mouse I have ever used in my life.

This tiny, foldable travel mouse is focused on one thing above all: portability. Just like a clamshell phone from the noughties, it can fold in half, allowing you to easily slip it into your pocket if you’re working on the go. But even though the Logitech Mobi Fold’s exceptional portability is its clear USP, I have to ask… is it actually that necessary?

After all, a lot of mice are already highly compact, and if you’re working on the go, you’ve probably got a bag to hold your laptop or tablet, right? I’d bet that your bag can fit a laptop and a mouse, so arguably, the thing that makes this mouse so special isn’t actually that game-changing.

Still, the Mobi Fold has a few interesting features to run through, and you’re surely curious as to how such a strange model feels in use. So, after using the Logitech Mobi Fold as my main mouse for a few days, here’s how I’d rate it — and whether I think it can compete with the best mice around.

First things first, the Mobi Fold is incredibly easy to get set up. There’s a sync button on it that makes linking up to a windows laptop, Mac, or Android device incredibly seamless. There’s also an easy switch feature, making it incredibly speedy to flick between a range of devices.

But after I got set up with the Mobi Fold, and started using it to get some work done I have to say… it wasn’t amazing.

The Mobi Fold exhibits a few key issues that make it feel inferior to a standard compact or productivity mouse. First of all, it has a slightly bizarre build. Its V-shape form makes it feel awkward to grip, and when using it for extended periods, this caused me to feel some discomfort in my hand. It lacks the ergonomics of my everyday mouse, the Razer Viper V3 Pro, and even lacked its fluidity, meaning moving it across my desk felt clunky.

In addition, the touch-controlled scrolling is a bit inconsistent. It doesn’t provide the same tight control of a traditional mechanical scroll wheel, and again feels a bit lacking in terms of fluidity. Don’t get me wrong: it’s totally functional, but if you want the smooth, precise scrolling of a traditional mouse, the Mobi Fold may leave you wanting more.

My final critique is on the feel of the left and right buttons. While these are serviceable, they felt more stiff than I expected them to, especially towards the back and middle of the model. I did appreciate the muted sound of clicking the left and right buttons, but I wish they felt a bit more sensitive.

Despite all of this, there are some clear positives worth pointing out. First of all, the mouse offers great battery life. It supplies about 22 hours of continuous use, which easily got me through the work week, meaning I didn’t need to charge it at all during the testing period. Having said that, Logitech says that you can get an extra three hours of use from just one minute of charging, making it exceptionally practical for someone like me who often forgets to juice up their devices.

In addition, the Mobi Fold features customizable button controls through the Logi Options+ app. This enables you to adapt pointer speed, set the central touch panel to different functions (like paste, volume controls, or a keyboard shortcut), and more.

In terms of design, I’m also a fan of the rubbery texture of the mouse, which is very pleasant to the touch. It’s also worth noting that 36% of the plastics used in the Graphite colorway of the mouse I used are made from recycled materials. It’s 29% for the Lilac and Off-White variants, which look pretty stylish in my opinion.

Look, the Logitech Mobi Fold does well to stand out from the crowd. Its lightweight and foldable design undoubtedly makes it easy to travel with — even though I’d argue that standard mice are probably portable enough as they are. In addition, the customizable buttons, long battery life, and satisfying feel of the mouse are clear positives.

But for $79.99 / £69.99 / AU$129.95, the Mobi Fold ends up feeling like a relatively poor value for money option. Really, that comes down to one thing: its lackluster performance. With underwhelming ergonomics, as well as slightly stiff scrolling and buttons, the Mobi Fold feels like an idea that’s far more impressive in concept than it is in practice.

Logitech Mobi Fold review: price & release date

• $79.99 / £69.99 / AU$129.95
• Released in June 2026
• Available in four colors

The Logitech Mobi Fold released in June 2026, carrying a list price of $79.99 / £69.99 / AU$129.95. That price means it’s competing in the same price bracket as great models we’ve tested, such as the Keychron M6 8K, but a lot more than our favorite ultra-compact mouse, the Logitech Pop Mouse. It's available in four colors, including Graphite, Off-White, Lilac, and Sand.

How I tested the Logitech Mobi Fold

• Spent days using it as my main mouse
• Tried out its various features
• Took on the go to test its travel credentials

I spent multiple days testing the Logitech Mobi Fold, using it as my main mouse in the office and when working from home.

During my time with the Mobi Fold, I used it for general productivity, exhausted its various features, and even took it on the go to assess its on-the-go credentials. I typically had the mouse connected to my Windows PC, but I also tried it out with an Android phone.

More generally, I’ve spent years testing gadgets here at TechRadar, where I serve as an in-house Senior Reviews Writer. I’ve tried out a wide array of computing accessories, such as the Turtle Beach Command Series KB7 keyboard, as well as gaming gear, premium wireless headphones, power banks, and more.

Go onto any forum or mechanical keyboard subreddit these days, and it can be a minefield as to what people recommend. It's an essential wall of noise with regards to size, shape, switch type and even more that can be daunting if you're a first-timer or you're someone getting back into the hobby after years of being out of it.

I was speaking to a fellow tech journalist at Computex 2026 a few months ago, and he raised this exact point with me. After being out of the hobby for several years, he'd come back to find it being more confusing than ever before, which completely switched him off.

Likewise, I've often thought we've reached a state of choice paralysis compared to where the hobby was, say, a decade ago. Back then, you had only a handful of switch choices, and while we've since seen the democratisation of hot-swappable sockets, machined aluminium chassis and open-source software, it can be horribly overwhelming when it comes to the decisions that actually matter — layout, switch feel, and budget.

Before I go any further, let me give you my credentials – I've been a tech journalist for the best part of a decade, reviewing keyboards from brands big and small, and I've been involved in the mechanical keyboard hobby since before it hit the mainstream. I've seen this market go from a small niche to something that can feel genuinely impenetrable if you're coming to it fresh.

To be truthful, it doesn't have to be that complicated. Underneath all of that noise, choosing your first mechanical keyboard still comes down to a few simple decisions, which I'll guide you through below.

1. Pick a size

It might seem a bit of a strange, but a good starting point is thinking about what size of keyboard you'd like. I don't mean the physical dimensions of the 'board, rather the layout and arrangement of the keys.

Keyboards can come in all shapes and sizes, ranging from the typical full-size 100% down to ridiculously tiny 40% keyboards. So, let's divide them into categories.

Firstly, we've got between 60% and 65% layouts, which eschew a lot of features, such as a function row, nav cluster and number pad in the name of saving as much desk space as possible. These layouts have been popularised by gamers who need desk space for sweeping mouse movements and find the elements mentioned above quite redundant. Between the two, a 65% layout adds arrow keys and some navigation keys, which I think are non-negotiable for productivity work, but your mileage may vary.

Moving up a tad, we go to between 75% and TKL, or tenkeyless, keyboards. These bring back the function row and navigation cluster, giving you a lot more functionality than smaller layouts, while still chopping off the number pad. Personally, this is my favourite option, and I think a strong middle ground if you want to save space without sacrificing too much. I use this kind of layout a lot of the time, for what it's worth.

Then, you can go bigger, up to 96% and full-size 100% options that give you everything and the kitchen sink, number pad and all. It's what you're most likely used to, and if the number pad has become non-negotiable, then it's one of your only options. Opting for a 96%, also known as a '1800 layout', keyboard can give you the number pad while moving some keys around to save a little bit of desk space, if you want a slight compromise.

2. Pick a switch

This is perhaps the most difficult section, as each switch feels different, and we've got so many options these days it can be hard to know what's best for you. Muddying the waters further, the old color categories aren't quite as clear cut as they used to be.

For instance, a Red switch would usually be light and linear, a Black switch a heavier linear switch, a Blue switch tactile and loud with an audible click and a Brown switch soft tactile, with a slight bump halfway down the keypress.

Now, however, we've got switches named after everything from all the colors of the rainbow to planets, birds and more besides, and it can be so difficult to understand the minutiae behind how each switch feels.

My genuine advice is to order a switch tester – there are lots of them floating about on the internet – which can give you a range of different types of switch in one convenient place, and help you decide what you like.

When you've selected a tester, pay attention to how each switch feels – the worst thing you can do is bash each of them in turn with as much force as you can. Pay close attention to how it feels under finger with regard to consistency of the operating force as you go down the travel, and whether you like something that's linear with a smooth keypress or tactile, be it with a click or a bump.

Once you've honed in on a switch you like, then you can do some digging into which keyboard features those switches. Or, if you're up for a little bit of work, then you can pick up a bare-bones chassis with a hot-swappable PCB – this means it comes with no switches or keycaps, which you'll need to supply yourself.

Going for something hot-swappable is a key piece of advice I think – it saves the hassle of soldering, and gives you more freedom and choice. It's also dead easy to assemble a keyboard this way, even if you haven't done it before. Each switch will have little pins on the underside – line these up with holes in the PCB and push straight down until you hear it click into place. I recommend picking up more than enough switches to give you some spares in case you bend pins when putting them into the hot-swap sockets on the PCB.

The point here is that everybody has a different preference for switches and how they feel. There are other considerations, such as lubrication, which can make a switch feel smoother, and the acoustics of a case and how this plays into the sound signature you'd like, but that's getting into the weeds a little. It's important to make sure your case doesn't have any rattle or ping and has some form of sound dampening, but that's as far as I'd go at this point.

3. Set your budget

Pricing is arguably as integral as any other point of consideration for choosing a keyboard, as your budget can decide what kind you end up getting. It's worth going in with a list of features you'd like; good things to look for include PBT keycaps, good wireless connectivity and a sturdy chassis.

It's possible to get some excellent affordable choices (i.e. around £50–£70 / $60–$80) that seem to pack in everything when it comes to features: hot-swappable switches, versatile wireless connectivity, addressable RGB lighting and all the rest of it, but outside of a few options, some seem to sacrifice build quality by being mostly plastic, which can feel quite cheap and scratchy. At this tier, I'd do your research carefully and lean towards boards with a reputation for punching above their weight rather than just grabbing whatever looks good on paper.

Spending a little more and going into the very low triple figures is likely to net you a strong choice from the likes of Keychron with advanced software support and a machined aluminum chassis. That aluminum build makes a tangible difference in practice — it adds rigidity, dampens unwanted noise and gives the keyboard a solidity that plastic boards rarely match. I'm a great lover of the likes of the Q1 Pro and others from its range, which are an excellent starting point in the mid-range.

Beyond that, you can go further into the hundreds with something fully custom or a pre-built choice from the array of boutique manufacturers you'll find online. This isn't what I'd recommend to someone just starting out in the hobby — rather, it's something to consider if you're already knee-deep and have some spare cash to put towards making something truly personal. But it's worth knowing that world exists, because once you've caught the bug, it's a very natural place to end up.

Final thoughts

There are some elements here, such as even more niche layouts, that I haven't even touched on in this article, which proves how deep the mechanical keyboard hobby goes. However, that isn't the point of this article – it's just a (reasonably) quick explainer of key things to look for when you're picking up your first mechanical keyboard.

If you're ready to start shopping, I've looked at plenty of options at a range of prices I feel are worth your time over the years, while the wider TechRadar crew has reviewed hundreds of keyboards that are worth a mention. The Keychron Q1 Pro is a strong starting point (or there's the Q1 Ultra 8K if you want even more features at a premium price). Likewise, at a more affordable price point, the Gamakay TK75 V2 and Epomaker P65 are well-reviewed choices that tick the right boxes in my book. For a more comprehensive overview, our best keyboards guide is regularly updated and a good place to browse.

Ultimately, though, you can go in any direction you want to, and that's the beauty of this hobby. Just stick to some of the advice given here, and you should be in good stead to get a keyboard that's feature-rich, has the feel you're looking for, and at a price that isn't out of your budget.

Boy, sure is a hot one today, huh? Okay, I get the irony: that's a take so cold you could use it to replace your freezing Wim Hof showers. But when the metaphorical mercury creeps this high, you've got to keep your cool. The same goes for your laptop, which is why you might want to grab a laptop cooling pad this summer.

Fortunately for you, I've spent this week testing every laptop cooling pad I can get my hands on to see which offers the superior AC for your computer. Not only that, but I've brought receipts — this piece has more graphics and graphs than election night coverage. So if you want objective numbers about which pad is genuinely gusty and which is all bluster, I've got the data you need.

I get that it can be tempting to overlook cooling your laptop during warm weather — I've been more worried this summer about tracking down a fan to keep myself cool than my laptops. But you overlook the best laptop cooling pads at your peril.

I still have vivid memories of the summer I redlined my laptop during a heatwave. While the video skittering should have been a hint, it was only when it stopped booting up and started bleeping SOS in Morse code that I began questioning my life choices. Turns out I'd burnt out the memory — quite literally: there were scorch marks on the inside of the case.

So at this time of year, it's worth considering whether a laptop cooling pad can help you out. And I can definitely help out there.

Lower values indicate better cooling.

Assessing which laptop cooling pad is a breezy wonder and which is a wheezy blunder ultimately comes down to how frosty each model's cooling is. That's why I went through every pad I could get my hands on to see how much each one prevented our gaming laptop from heating up during a 3DMark stress test.

As you can see, by far the weakest cooling offered by any laptop cooling pad I tested was from the TopMate C12 Laptop Cooling Pad. Compared to the 57.4°F / 31.9°C baseline rise of our gaming laptop alone, the C12 was only able to limit it to a 41°F / 22.8°C rise — that might be better than frantically waving a dish towel in its general direction, but only barely.

Probably the biggest disappointment of these tests was how the Klim Mistral performed. Not only did it seem to perform worse than the more affordable Klim Wind — resulting in 36.7°F / 20.4°C warming compared to the Wind's 35.1°F / 19.5°C — but it was pretty inconsistent to boot, achieving even worse results on a retest.

Skipping ahead a little, the laptop cooling pad I was most surprised by was the TECKNET. Although it's cheaper than quite a few of the pads I tested here, setting me back just $21.59 / £21.99, the 32.2°F / 17.6°C warming it presided over put it firmly in the top half of the pack. It's the little laptop cooling pad that could.

Given that the Liangstar Laptop Cooling Pad and Klim Ultimate both achieved an almost photo finish, it would be easy to assume there's not much daylight between them. However, like a bottle of wine, you really need to weigh up what you're spending here to calculate its true value. And as the Liangstar costs $20.99 / £23.59 versus the Klim Ultimate's $44.97 / £44.97 price tag, that definitely takes the edge here.

But, frankly, there's a reason Llano is the absolute GOAT in my eyes. As you can see, it took both first and second place on my cooling pad podium. While the Llano V10 Gaming Laptop Cooling Pad stopped our gaming laptop from warming up more than 21.6°F / 12°C, the Llano RGB Laptop Cooling Pad kept it down to just 14.4°F / 8°C of warming. This boi makes liquid nitrogen look positively toasty.

You may think that your gaming laptop makes a lot of noise. But believe me: that's scarcely more than a murmur compared to some cooling pads. Given they're essentially just an LED-adorned box with a whopping great fan inside, they can get pretty shouty. That's why I grabbed the sound level meter from my utility belt and started measuring like the world's nerdiest superhero.

Perhaps predictably, the pad that blows coolest blows loudest. While I love the Llano RGB Laptop Cooling Pad's glacial chilling, I can't get away from the fact that it's pretty noisy. I'm 5 foot 11 inches tall, and from my head height, I clocked it at 71dB — according to the Center for Hearing and Communication, that's roughly as loud as a coffee grinder or freeway traffic. In my book, that's a worthy price to pay for keeping your laptop cool, but it might not be ideal if you're planning to use it in the office.

In fact, you might assume there's an inverse relationship between cooling and fan noise. And while that does hold true for the most part, there are some interesting exceptions. For example, while I found the Liangstar Laptop Cooling Pad offered the third best cooling in my tests overall, it was substantially quieter than either of the Llanos, clocking in at a much less brash 45dB.

Conversely, the Klim Mistral manages to buck the trend in the other direction, running surprisingly loud compared to some of the other competitors here. At 52dB, it kicks out a similar level of noise as a fridge — which is pretty ironic given it offered some of the worst cooling in my testing.

And there are some surprising candidates for the winner's podium when it comes to sound levels. The TECKNET offers far from the worst cooling, and yet it ties for first place as the quietest pad on test here at 36dB — again, not at all bad given its super affordable price tag.

Honestly, though, if you want whisper-quiet running without sacrificing performance, my pro tip would be to check out the Klim Ultimate. Unlike Klim's two cheaper cooling pads, it offers very credible chilling while also measuring noise levels of 36dB from head height — that's apparently quieter than a library, which isn't known for being a raucous place.

Fundamentally, noise levels probably shouldn't be the deciding factor when picking your perfect laptop cooling pad. Both cooling power and budget come higher up the pecking order in terms of my personal preferences. But that doesn't mean you should ignore it completely — depending on where and how you use your laptop, you could find strapping a jet engine to the bottom of it to be a bit of a deal breaker.

Do I even need a laptop cooling pad?

Re-encoding a 4K stereo .mov file at highest quality, the Acer Predator Helios 300 showed essentially no reduction in either average FPS or estimated encode time, suggesting limited heat-related throttling took place.

So it's pretty clear which cooling pads offer ice-cold AC and which sound like a tumble dryer breaking the sound barrier. But I've left the biggest question until last — do you actually need one at all?

Aiming to prove my theorem that 'cold CPU = good', I whipped up a quick encode test designed to stress out the CPU of several laptops over a longer period. In theory, after an hour, their core temperature should have risen, their CPUs throttled, and the length of the encode spiked and the encode rate dropped. Running the same test with one of our top cooling pads, the Klim Ultimate, would then show how much it could reduce this throttling.

On my MacBook Air M5, after an hour of using its passive cooling alone, the total estimated encode time had crept up to 122 minutes, and the average encode rate was sitting at 2.52 FPS. When I reran the test with the Klim Ultimate running on max cooling, that total encode time was trimmed to 114 minutes, and the encode rate had increased to 2.77 FPS. That's not a huge difference, but it shows the Klim Ultimate was able to trim back some of that temperature-related throttling.

Running the same test on our Acer Predator Helios 300 was a much more ambiguous experience. During my first run, the encode crashed within minutes, and during the second it crashed moments after the test concluded. So it was honestly far from stable.

I was able to eventually get some results, however, and they showed... nothing. Whether I was using the Klim Ultimate or not, the test results were essentially identical, with Handbrake clocking an estimated encode time of 115 minutes uncooled and 113 with the Klim's help. Meanwhile, the encode rate remained steady, sitting at a reasonable 2.8 FPS.

What does that mean? That I've wasted several hours of my life? Not quite. There are a couple of key conclusions to take away from this. One is that a performance laptop with whacking great fans built in is already pretty good at keeping itself cool. Shocking revelation, I know.

But probably the more critical takeaway is that the mileage you get out of a laptop cooling pad is going to vary depending on how well optimized it is for handling heat, as well as the kind of tasks you're doing. Had I tried to run Cyberpunk 2077 on max graphics settings with ray-tracing switched on, the Predator Helios 300 would likely have caused it to melt into the earth's core.

There's also another caveat. While it's definitely been warm the last week or so in the TechRadar testing lab, it hasn't reached the kind of desiccating highs that have hit both the US and UK in recent months. Past a certain point, any laptop will struggle in the heat. Forget CPU throttling — in that heat, I'd be more worried about your components liquefying like a chocolate bunny on the launch pad at Cape Canaveral.

In light of that, I'd say a laptop cooling pad is still worth exploring, especially if you tend to do a lot of resource-intensive tasks like 3D work, Photoshopping or gaming.

Microsoft's latest revolutionary idea for Windows 11 is to have a key on your keyboard which can be remapped to do absolutely nothing.

Windows Latest noticed the latest twist in the tale of the Copilot key, as highlighted by regular leaker PhantomOfEarth on X, who spotted the development hidden in a recent Windows 11 preview build.

In the choices to customize the Copilot key – which, by default, summons Windows 11's Copilot AI (of course) – there's a new option to simply 'Do nothing'.

Yes, that's correct – you can change the key to simply be a pointless piece of plastic that does precisely zip. (Or at least you'll be able to in testing, when this ability comes into play, that is, although some Windows 11 testers have reportedly seen it live in preview already).

As you may have seen earlier this year, Microsoft is working on bringing fresh options to the Copilot key that include customizing it to invoke the context (right-click) menu, and to turn it back into Right Ctrl (which was the key that the Copilot button replaced on Copilot+ laptops and some keyboards).

Analysis: do nothing, be happy

What's the point of a key that does nothing? Good question. Maybe it's the keyboard equivalent of a stress ball – you can hammer on that key as much as you want when you're really annoyed, and it won't splurge a load of characters into the document you're working on as you exorcise your frustrated demons.

Okay, so maybe not, but perhaps the idea is that this is aimed at people who really hate the Copilot key, but haven't decided what they might want to remap it to. So, they can go ahead and elect for the key to do nothing if it's accidentally hit, while they figure out what they might want to redefine in its place. That's stretching things, admittedly, but it's the best guess I have.

At any rate, it's a harmless enough option, although it feels inescapably odd to have a 'blank' key on your keyboard. How far we've fallen since the Copilot key was first revealed and trumpeted by Microsoft as the biggest thing to happen to keyboards in 30 years since the Windows key was introduced. And indeed more recently, Microsoft promoted the Copilot key as the "button you can press to fix everything", so there's some irony that it could soon (optionally) become the button you can press to fix 'nothing' in a very literal sense.

Don't forget that you don't have to wait for Microsoft's Copilot key remapping functions to arrive in the release version of Windows 11. You can use the Keyboard Manager in PowerToys to do this instead, although it'll be far neater to have these options in Windows 11's settings, of course.

Razer Kiyo V2 webcam: Two-minute review

Razer is a household name in the webcam space, with its Kiyo brand being one of the most popular choices for streamers and PC gamers. The latest Kiyo V2 is another sterling example of Razer's commitment to premium build quality and high-end components, and for the most part, it's a great product.

Delivering either 4K recording at 30 frames per second or 1080p at 60, the Kiyo V2 captures quality video with a high degree of customization via the Razer Synapse software. It's fairly pricey (don't expect to see it on our list of the best cheap webcams), but for a 4K webcam with this sort of build quality and feature set, it's actually quite competitively priced.

Coming in black, white, and pink colorways (mine is the pink 'Quartz' model), the Razer Kiyo V2 is an extremely well-constructed product. It's durable and pleasingly tactile. The base can be extended and rotated to capture the perfect angle, and it easily clasps onto any monitor; I tested it both with the two monitors in my home desktop setup and my laptop, and it snapped into place with no issues. It's a little heavy, however, so laptops with flimsier display hinges might struggle.

The design is a departure from previous Razer webcams, which typically opted for a singular large casing surrounding the lens construction. Instead, it's a smaller lens housing with an oblong body, immediately reminiscent of the Logitech MX Brio 705.

Not everything has been abandoned with this new design, however. The lens housing, like previous Kiyo models, includes a pleasingly tactile rim that can be twisted to close the built-in physical privacy shutter. I'm always a fan of privacy solutions like this, though given the large size of the glass lens face, it would've been nice to see a lens cap included to keep it dust- and scratch-free.

It would potentially be nice if the webcam could be detached from the attached mount in order to fit it to a different mount; many content creators will have their own video setups and may want to use their own camera stands. However, the mount does have a threaded screw connector on the base, letting you fit it atop most industry-standard camera mounts.

In terms of video quality, it's great. 4K video is sharp and colorful, and even zoomed in, I found I looked perfectly detailed in the footage I recorded. Color reproduction is great, and the camera performed well in a range of light conditions. Low-light performance resulted in some mild oversaturation, but I've seen worse performance in more expensive cameras. It also supports HDR, though only at 30fps even at lower resolutions.

The autofocus works well, but I found it was a little slow to adjust if I quickly moved closer or further from the camera. Having tested quite a few webcams in my time, I feel that a webcam in this price range should be a bit snappier to focus.

That big lens means that the default field of view is huge. A 93-degree FOV means that the Kiyo V2 is liable to capture not just yourself but the entire room you're in, but thankfully it's easy enough to tweak this via the zoom and crop tools in Razer's Synapse software.

On the topic of Synapse, it's still a frankly rather clunky piece of software, but for webcam users who want granular control over their hardware, it does a solid job. In addition to zoom and crop tools, you can also manually tweak the autofocus, auto exposure, and color balance.

The Kiyo V2's software-side feature set also includes a selection of AI-powered tools, which are covered prominently in the marketing material for the webcam. These include dynamic light correction and noise reduction, but these features already existed in Synapse, and to be honest, I'm not entirely clear on what AI brings to the table here.

Look, Razer: I get it. I'm sure there's tremendous pressure from your shareholders to make everything AI-powered, because it's the buzzword du jour. But anyone who actually wants AI in their webcam (for whatever inane reason) likely isn't going to be better served by the Kiyo V2 than any other cutting-edge 'AI' webcam, like the Obsbot Tiny SE.

One element that does actually benefit from the involvement of machine learning is the auto-framing feature, which uses AI-powered head-tracking to keep you in the center of the frame even if you move around. However, since the Kiyo V2 lacks a mechanized gimbal, it can't alter the frame while fully zoomed out and can only track you so far; it can keep you in center frame if you move by a foot or two, but it won't follow you around a room.

On the bright side, you don't actually have to use Synapse and the AI features at all. The Kiyo V2 works great straight out of the box; just plug in the bundled cable, and you're off to the races, assuming you're happy with the default wide-angle FOV.

Now, for the only real problem I have with the Razer Kiyo V2. It comes with a USB-C to USB-C cable in the box (the one with my review unit is pink, like the webcam itself), and as far as I can tell, you have to use this cable to access the full 4K functionality of the camera.

Considering that the cable is USB-C-exclusive, you'll need a free USB-C 3.0 port to make full use of the Kiyo V2. I tested it out with a USB-C to USB-A adapter, as well as using one of my own USB-C cables; no dice. It's frustrating, because USB-C ports can be in short supply for users connecting multiple peripherals, and the bundled cable is a bit short and inflexible.

Lastly, the built-in microphone is... fine, I guess. It's good enough for video calls, but anyone aiming to produce professional-level video content should definitely use a proper standalone microphone.

It's fair to say that the Razer Kiyo V2 deserves a spot among the best webcams on the market. There are a few niggling issues, but nothing that should ruin the experience for a gamer who wants a high-end webcam. For hardcore content creators, it remains a sound choice, but you should be aware of the downsides.

Razer Kiyo V2 webcam: Price & availability

• How much does it cost? $149.99 / £149.99 / AU$279.95
• When is it available? Available now
• Where can you get it? The US, UK, and Australia

At $149.99 / £149.99 / AU$279.95, the Razer Kiyo V2 is significantly cheaper than the brand's own older Kiyo Pro webcam. If you're looking for a high-quality 4K cam, it's not an unreasonable price.

Sure, you could easily get a cheaper 4K webcam, but you'll need to risk it on a less established brand, and you almost certainly won't be getting the same rich feature set seen in the Kiyo V2. Similarly effective models from other premium brands like Logitech and Elgato will cost a comparable amount, so I'm pleased to say that despite its reputation for pricey hardware, Razer got the price right this time around.

Razer Kiyo V2 webcam: Also consider

How I tested the Razer Kiyo V2 webcam

• Tested the webcam in video calls and recording
• Compared image quality to other webcams
• 8+ years of experience reviewing computer hardware

I replaced my usual webcam (the Insta360 Link 2 4K) with the Razer Kiyo V2 for two weeks, using it for all my normal video calls during the workday. I also tested it in various different lighting conditions by recording video separately and comparing the clips side by side. Naturally, I installed (well, reinstalled) Razer Synapse to properly test out all the software-side features as well.

I've been testing and reviewing PC hardware for more than eight years, starting at the PC-building hobbyist magazine Maximum PC before making the leap to TechRadar's computing team. I put all of my knowledge and experience behind each and every one of my product reviews, so you can be assured that you're getting an informed and bias-free judgement.

• First reviewed July 2026

Simply put, polling rate is the frequency at which data is sent between your mouse and keyboard to your computer. For many years, the standard polling rate of most gaming mice and keyboards was 1,000Hz, and that's still a setting that's available by default.

However, with the rise of competitive shooters, particularly tactical ones such as CS2, VALORANT, and Rainbow Six Siege, the pro scene needed a shift, and we saw the advancement towards 4,000Hz and 8,000Hz for "esports tech".

The best gaming keyboards and the best gaming mice are marketed for their 8K or 8,000Hz polling rates, particularly in models aimed at esports pro players. If you look at the current gear in circulation, it's easy to see how it's caught on: the Razer Viper V4 Pro, and the Logitech G Pro X2 Superstrike are recent examples of pointers, and the Razer Huntsman V3 Pro Tenkeyless, Corsair Vanguard Pro 96, and Cherry XTRFY K63W Pro Compact Ultra-Wideband for decks that tout this feature.

But does anyone really need an 8,000Hz polling rate when gaming? Do the best FPS players in the world even take advantage of it? I'm going through everything you need to know about how 8K works, the latency you can expect, impact on battery life, and all other things you need to consider when properly getting your setup ready for success.

How does polling rate affect latency?

True to its namesake, an 8K polling rate will report its position to your PC a total of 8,000 times, instead of 4,000 times or a thousand times as with 4,000Hz and 1,000Hz, respectively. An 8,000Hz polling rate responds with far lower latency than either of these two previous standards; specifically, updates are sent between a mouse or a keyboard to your computer's processor every 0.125ms, eliminating a theoretical maximum of 0.875 ms input delay, meaning a smoother cursor or movement.

The difference in response time of 0.125ms (8K), 0.25ms (4K), and 1ms (1K) can be huge when it comes to polling rate, provided you have the right hardware to properly take advantage of this. That's because an 8,000Hz polling rate can be incredibly demanding on the battery life of wireless mice and keyboards, and it's one of the main considerations as to why you may want to drop the response time down in your settings.

The drawbacks of an 8,000Hz polling rate

In brief, an 8,000Hz polling rate for your mouse and keyboard can be incredibly demanding on your computer. That includes heavy strain on even the best processors, the aforementioned heavily reduced battery life on a mouse and keyboard, and even the potential risk of micro-stuttering. As a lifelong PC gamer and a competitive shooter enthusiast who is hopelessly obsessed with VALORANT, I've seen the battery life debate happen in real-time.

I've tested and reviewed hundreds of mice and keyboards throughout my career, and one of the biggest points of contention when it comes to enabling the polling rate comes down to battery life. As an example, my favorite gaming mouse of all time is the Corsair Sabre V2 MG, an 8K-enabled gaming mouse that's built with a Magnesium Alloy frame. It weighs just 56g and features excellent skates, making it ideal for a precision heavy shooter.

As standard, via the Corsair Web Hub, this gaming mouse will run out of the box at 1,000Hz (1K), with battery life prioritized. With the pointer used as the stock, you can expect around 100 to 120 hours of play between charges. In my experience, I am charging this mouse every two weeks or so, depending on how much I'm working day-to-day, etc. However, in my many months with this mouse, I've noticed that things fall off incredibly hard with 8K enabled; my battery life tends to last only around two to three days (or one or two nights of VALORANT Competitive) before I'm reaching for the USB-C lead.

If we take 18 hours as the average battery life from the Corsair Sabre V2 MG when used in 8K mode, that's a reduction of around 85%, which is staggering. We can see a similar drop off from the most well-used new esports mice currently on the market, with the Razer Viper V4 Pro (an excellent mouse), touting up to 180 hours of playback in 1K but only 45 hours when maxed out at 8K. Similarly, while the Logitech G Pro X2 Superstrike has around a 90-hour playback at 1K, that drops down dramatically to between 20 and 35 hours at 8K. With Logitech's pointer, though, you have to factor in the strength of the haptics here, hence the rough range rather than a more exact figure.

What about the human limitations of an 8,000Hz polling rate?

Now that we've covered what an 8,000Hz polling rate is, how it works, how it compares against 1K and 4K, and the technical drawbacks, we now need to go over the human limitations with 8K. As previously mentioned, 1K means a 1ms response time, and that gets cut down to just 0.125ms with 8K, but what does that mean for a human being, and not a machine?

The average human response time is around 250-280ms; that's the time it takes to see something and physically react. I am not a pro player, but I do play video games at a high level, with a response time average of around 175ms, though I've been faster. The best esports players can eclipse this effortlessly: you only need to look as far as VALORANT and CS2 players, such as TenZ (widely considered to be among the best VALORANT players), with an average reaction time of 135ms. 100ms is even possible, even though the average tends to hover around the 150ms mark.

If we take 1K as a baseline for polling rate, that means there's an average of 150 reports between the mouse/keyboard and the processor, as you tap a key or click what you see. Taking 8K, then, sees 1,200 instances. With this information in mind, is there really much of an advantage here, even at this granular level, with the best players in the world and, conversely, the only people who would even notice a proper difference between 1K, 4K, and 8K?

Do pro players use 8,000Hz polling rates?

Considering the far lower latency, you would expect that professional esports gamers would all dial their settings to an 8,000Hz polling rate by default when playing demanding games, but that's simply not the case. If we look back at TenZ's mouse and keyboard settings when playing VALORANT, he last used the Pulsar TenZ Signature Edition mouse at 1,600 DPI, 0.24 sensitivity, and (most crucially) a 1,000Hz polling rate as standard; no 4K, and certainly no 8K enforced here.

What about a VALORANT player from the most aggressive team in the game? Then we must look at f0rsakeN from the legendary Paper Rex. He was last using the Pulsar Sustanto-X with an 800 DPI, a 0.71 sensitivity, and a 4,000Hz polling rate. Let's move away from Riot Games' shooter and instead turn our attention to Valve, then. As far as CS2 players go, few are as well-regarded in 2026 as Team Spirit's donk.

The young Russian is widely regarded as the best player in the world. Is he using an 8K polling rate for his mouse and keyboard to do this? No, while he previously used the industry standard Logitech G PRO X Superlight 2, he's now switched to a bespoke, and as of yet unreleased/prototype Zowie X Donk mouse at 800 DPI, 1.25 sensitivity, and a 1,000Hz polling rate. What about Niko? He recently had his own Razer collaboration drop, and currently uses a Razer Deathadder V4 Pro Niko Edition with an 800 DPI, 0.9 sensitivity, and a 2,000Hz polling rate.

Let's briefly look at two games for the sake of argument, and two of their respective top players. Peterbot is widely considered the best Fortnite player in the world, and he uses a Logitech G Pro X Superlight 2 at 800 DPI with a 1,000Hz polling rate. ImperialHal is among the best Apex Legends players, and the CEO (as he's known) currently uses a Finalmouse Starlight Pro with an 800 DPI, a 1.1 sensitivity, and a 1,000Hz polling rate. So, pro players simply are not using an 8,000Hz polling rate when playing, and they're simply better than the other 99.9% of players who play these games.

Is using an 8,000Hz polling rate worth it?

Based on everything I've gone through here, it becomes challenging to wholesale recommend (or actively condemn) 8K. An 8,000Hz polling rate is mechanically and technically better for how it responds between the peripheral and the machine, even if the human who presses that key or clicks the mouse ends up being the limiting factor, or bottleneck. It's the simple, undeniable truth that the saved milliseconds are (really) indistinguishable to basically everyone on the planet.

Then we get into the debate of battery life. Do you want your gaming mouse to last over 100 hours on a single charge, or just 10? That's a tough sell, considering it undercuts the primary reason to cut the cord in the first place. Then there's the massive CPU overload, game engine incompatibility (and developers and publishers are not yet gearing their software for the tech), and the variables of the hardware itself. Hardware makes the difference: TMR and Hall Effect switches and sensors will have far more of an impact than the simple reporting time between the processor and peripheral.

So why am I not fully discouraging you from using an 8,000Hz polling rate in its entirety? Because it ultimately comes down to personal preference, and to feel. If you're running one of the best gaming PCs or best gaming laptops with a high-end processor, a 4K graphics card, and a high refresh rate monitor, then, battery life aside, it doesn't really hurt to have everything cranked up and forgotten about. Are you likely to really notice it? No, but fractional optimization is still (ever so slightly) better than none in the first place.

I'm not quite cynical enough to claim that an 8,000Hz polling rate is just a marketing gimmick; however, I will say that hardware companies have gleefully exploited the ignorance of the end consumer, the simple reductionist view that a bigger number automatically means better, without looking into the nuances of the conversation. Now that's something you will be fully clued up on when considering your next keyboard or mouse.

• Users says they've observed LG gaming monitors automatically installing unwanted software on PCs
• LG's terms of service warn that conversations may be "captured and processed" on TV with the latest version of webOS
• The terms say you must now warn guests they may be recorded "in compliance with applicable wiretapping… laws"

How smart should a smart TV be? According to LG's latest TV terms and conditions, the answer is "not quite smart enough to comply with wiretapping laws", because that's now your responsibility if LG captures the voice of a guest in your house through its AI voice services. Though the situation with LG monitors appears to be even more dramatic.

As Gamers Nexus reports, some LG monitors appear to be installing adware on Windows PCs without asking for permission: in addition to the LG Monitor App Installer, they also install McAfee Scam Detector.

LG's own app requires full access to all system resources, which potentially includes all your online activity, logins, hardware, location and more — while McAfee has a long history of being installed on devices as 'bloatware', and people are not reacting positively to suddenly finding it on their PC.

Comment from r/LGOLED

There may be a perfectly innocent explanation for all of this, but when big tech firms keep getting caught doing bad things because they thought they could get away with it, it's no wonder people are assuming the worst.

Comment from r/hardware

The bit that's causing consternation regarding smart TVs is part 6(d) of the new LG Electronics terms of service, headed Voice Recognition and Privacy Compliance.

As Notebookcheck's Hannes Brecher notes, the section states that it's your responsibility "to obtain all necessary consents from any third parties whose voices may be captured by the Product and to notify household members and guests that their voices may be captured and processed, in compliance with applicable wiretapping, eavesdropping, and privacy laws."

There are three ways around that. One, you can turn off all microphone-based features. Some people won't mind that, but they can be useful — especially asking it for settings you don't know how to find.

Two, you can avoid installing the latest software — but that means you won't get any security updates, which are important (to protect your privacy, ironically, among other things).

Or you can disable your TV's connection to the internet so it can't send information back, but that obviously makes it less useful, and will also disable the voice controls anyway.

I think the terms and conditions are an attempt at corporate ass-covering rather than something sinister: the preceding paragraph talks specifically about when "a product with voice recognition functionality is used" and it's possible that "family members, guests, children, and bystanders" might be overheard; if you're choosing to activate AI-based voice features then of course voices are going to be captured and processed in order for those features to work.

At the same time, it does seem broad enough to let LG use people's voices as AI inputs, rather than just accidental capture. And in the context of what LG's doing with PC monitors (not to mention AI training's very, ahem, casual relationship with consent and copyright), that's a worry — and people online increasingly have no tolerance for anything like this, as the responses on Reddit and Gamers Nexus' original YouTube video have shown.

We've approached LG for comment on these claims, and will update the story when we hear back.

Comment from r/hardware

The gaming monitor market is filled with high-quality displays that offer enough features to provide the most immersive gaming experience. OLED monitors are right at the forefront of monitors in achieving the latter, with exceptional deep black levels thanks to their high contrast ratio.

It's not all just about the panel type, though. The display resolution, refresh rate, response times, and brightness levels all play a significant part in allowing monitors to blossom, and all of those aspects also determine pricing (outside of potential market condition changes).

That's exactly where the LG UltraGear 45GX950A-B comes into play. It's a 5K2K ultrawide OLED monitor, which means its display resolution is 5120x2160, with even sharper image quality than a 4K display. It's easily one of the best gaming monitors in 2026, and is the kind of monitor that would define an 'ultimate endgame' gaming experience in terms of visuals.

Despite the obvious and eventual GPU upgrade I'll have to make when using a 5K monitor, it hasn't stopped me from keeping my eyes peeled for it, particularly whenever it receives a significant price drop.

Fortunately, it's Prime Day, which means you can find it for $1,429.69 (was $1,999.99) on Amazon in the US, and for £1,472.49 (was £1,649) in the UK. However, the competition on the horizon is enough to make you consider waiting a little while before jumping all in on the UltraGear display.

Having used the LG UltraGear 45GS95QE OLED ultrawide — which is very similar to the GX9, with the only difference being its 3440x1440 resolution — I can say that the step up in resolution would make LG's 5K2K display worth every cent, despite its high price.

With the new Alienware AW3926QW 5K2K OLED ultrawide slated for launch by the end of June, LG's top-of-the-line monitor might have its money's worth. Thanks to the AW3926QW's 39-inch display size, there's a higher pixel density at 5K2K, meaning image quality will be much sharper than what the LG GX9 has to offer.

It is an RGB stripe tandem OLED panel, which reduces text fringing and provides significantly higher and more consistent brightness compared to other OLED monitors.

Most importantly, the big takeaway is that the AW3926QW's price is rumored to be at $1,100 (around £824 / AU$1,572). That's a very generous and affordable price tag, since other monitors with the same specifications are far more expensive.

The great thing is that more details on pricing should be coming very soon, so there's a good reason to weigh the options between the two monstrous displays.
