‘Clears a room of cooking smells in minutes’ — I reviewed Coway’s air purifier for larger rooms and was wowed by how quickly and quietly it sensed and snuffed out impurities and odors

Thermacell has launched Liv 2.0, the next generation of its Wi-Fi-connected smart mosquito protection system. It features new hardware and can cover a larger area, and Thermacell says its formula can now deter no-see-ums. But it's also more expensive and requires professional installation.
Liv 2.0 uses the same setup as the original Liv - a central hub with a wired repeller system containing its metofluthrin-based repellent - but it features entirely new hardware. Pricing starts at about $1,746 for a system with three repellers, a six-pack of repellent refills, and coverage of up to 900 square feet. That's twice as much as the original, wh …


The best deal at RYOBI Days at The Home Depot right now isn’t a price cut, it is a free tool. Right now, you can buy one of the qualifying RYOBI ONE+ 18V kits and pick a second ONE+ tool at no extra cost. The priciest free options on the higher-tier kit are worth up to $229. I haver a number of Ryobi tools in my kit and they almost always perform way above their price tag. And that’s even before the discounts. The free-tool menu changes as stock moves, so the good picks tend to disappear before the kits do.
57% off the most useful entry point, and it unlocks a free ONE+ tool
The RYOBI ONE+ 18V Starter Kit (PSK1212SB) is the one to grab first at $99, down from $228, because it covers the two battery sizes you actually use. You get a 4.0Ah HIGH PERFORMANCE pack for high-draw tools like saws, a lighter 2.0Ah pack for drills and lights, and a charger, and the kit qualifies for a free ONE+ tool worth up to $89. Any RYOBI 18V ONE+ battery runs the entire 300-plus tool ONE+ catalog, so this is the cheapest honest way into the system.
A finished yard tool at $99 that still comes with a free ONE+ tool
The RYOBI ONE+ 18V 13-inch String Trimmer (P20150) is the better $99 buy if you also need to cut grass, since it ships ready to run with a 2.0Ah battery and charger and still qualifies for a free ONE+ tool. It handles edging and trimming on a typical lot, and the included battery drops straight into any other ONE+ tool you own. Pairing it with a free blower or hedge trimmer from the offer list basically builds a starter yard kit for the price of one tool.
Three batteries, 45% off, and the longest free-tool menu in the event
The RYOBI ONE+ 18V HIGH PERFORMANCE Starter Kit (PSK108SB) is the pick if you want the strongest free tool, because at $199 it opens a 20-item menu that includes options worth more than the kit itself. You get three HIGH PERFORMANCE batteries (one 2.0Ah and two 4.0Ah) plus a charger for $199, down from $361.97, and the free-tool list runs up to a $229 battery two-pack. If you are starting from zero and want to skip the upgrade later, this is the kit that pays for itself fastest.
The RYOBI Days free-tool offer is structured around three qualifying purchases: the $99 ONE+ Starter Kit, the $99 ONE+ String Trimmer, and the $199 HIGH PERFORMANCE Starter Kit. Add a qualifying kit to your cart, then choose one tool from that kit’s eligible list and it lands in the order at $0. The $99 kits draw from a 13-tool menu topped by an $89 reciprocating saw, while the $199 kit expands the menu to 20 tools and adds the high-dollar options. Stock is the only real catch, since the offer is limited to what The Home Depot has on hand and the best free tools sell through first.
With either $99 kit, the RYOBI ONE+ 18V Reciprocating Saw is the highest-value free pick on the 13-tool menu at a regular $89.00, followed by the 18-inch Hedge Trimmer at $79.97. Every option below is a real ONE+ tool that runs on the battery your kit already includes, and the price shown is what you would otherwise pay.
Step up to the $199 HIGH PERFORMANCE Starter Kit and the free RYOBI ONE+ 18V 4.0Ah Battery Two-Pack becomes the standout claim at a regular $229.00, more than the kit costs. The same menu adds the brushless Pet Stick Vacuum at $199.00, the 4-Mode Impact Wrench at $179.00, and the 7-1/4-inch brushless Circular Saw at $139.00, none of which appear on the $99 list.
Other tools on the $199 menu worth a look include the RYOBI ONE+ HP 18V Brushless AirStrike Brad Nailer, the RYOBI ONE+ HP 18V Brushless 130 MPH 510 CFM Leaf Blower, the RYOBI ONE+ 18V HP Brushless Hybrid 9-Inch WHISPER SERIES Oscillating Fan, and the RYOBI ONE+ 18V Cordless Telescoping Power Scrubber. All four run on the batteries the kit already includes.

Ooni’s Memorial Day sale is the last sitewide cut before late summer, with every current-generation oven 20 percent off and a few legacy models cut deeper. The cheapest current-gen Koda 2 drops to $399.20 (was $499), the 1st-generation Karu 12 hits $249 (was $349) as the cheapest path into real wood-fired pizza Ooni currently sells, and the bundle pages stack that 20 percent on top of accessory packs that were already discounted. The Karu 2 Pro is the multi-fuel pick in PopSci’s best pizza ovens guide, and Memorial Day weekend is the cutoff, so the next few days are it.
The Koda 2 is Ooni’s cheapest current-generation gas oven and the one most first-time buyers should land on, with a 14-inch deck that fits a true 12-inch pie and dual-zone burners that let you drop the back flame so crusts don’t char. At $399.20 it’s $99.80 off, which is the same dollar cut Ooni has run at past sales, and the under-$400 price keeps it firmly in starter-oven territory without dropping back to the 1st-generation hardware. If you want a current Ooni and have never owned a pizza oven before, this is the default.
The 1st-generation Karu 12 is the deepest cut in the entire Ooni sale at 29 percent off, and at $249 it’s the cheapest path into real wood-fired pizza Ooni currently sells. It cooks the same Neapolitan-style pies as the 2nd-generation Karu 2 in roughly the same time, just without the redesigned chimney and viewing window. For anyone who wants to try wood-fired before committing to the current-gen platform, or who simply wants a backup oven that runs on charcoal when the propane tank goes empty mid-cookout, this is the price to act on.
The Koda 2 Essentials Bundle wraps the same 14-inch Koda 2 above with the peel, turning peel, brush, infrared thermometer, and gloves, which together would cost $245 outside the sale. The bundle saves $122.80 versus buying the oven and accessories separately, and at $491.20 it’s the cleanest “everything you need to launch a pizza this weekend” pick in the sale. It’s worth the upgrade over the bare oven if you don’t already have a peel and don’t want to spend Memorial Day weekend chasing accessories at full price.
Every current-generation oven is 20 percent off, with the three legacy 1st-generation models cut deeper. The Karu 12 lands the deepest at 29 percent off, and the 1st-generation Koda 16 at $499 is the cheapest 16-inch gas oven Ooni still sells.
Bundles are where the biggest dollar savings hide, since the 20 percent sitewide cut layers on top of accessory packs that already discount their contents. The Koda 2 Max Outdoor Kitchen Bundle is $383.80 off (the largest dollar cut in the sale), the Koda 2 Max Essentials Bundle is $288.80 off, and the Karu 2 Pro Ultimate Bundle is $265.80 off, all bigger cuts than any standalone oven. The Volt 2 indoor electric oven only shows up via these bundles in the sale, since it isn’t discounted on its own.
Every peel, cutter, and serving tool is 20 percent off. Ooni’s perforated peels are the ones to grab if you’ve been launching pies off a solid peel and watching them stick, since the slots let semolina fall through instead of riding the pie into the oven and burning. Smaller bundles like the Pizza Peel Bundle and the Brush and Turning Peel Bundle stack additional savings if you need more than one tool.
Cast iron is what turns an Ooni from a single-purpose pizza oven into something you can roast, sear, and bake in. The Dual-Sided Grizzler Plate at $64 is the most versatile single pan (grill marks on one side, smooth searing surface on the other), and the Roasting Pan opens up the Koda 2 Max for whole chickens and trays of vegetables at 900 degrees.
Dough boxes, scales, and topping stations all see 20 percent off, with Ooni’s frozen Dough Balls 24-pack down to $79.20 if you’d rather skip kneading entirely. The Pizza Topping Station at $120 is the kit that makes assembly-line pies for a backyard party feel like running a real pizzeria instead of crowding a kitchen counter.
Gas burners, conversion kits, and replacement baking stones are all 20 percent off, which matters if you already own a Karu and want to add the gas option, or if your existing stone has finally cracked. The $112 Karu 2 Pro gas burner is the cheapest way to convert a wood/charcoal Karu 2 Pro into a weeknight gas oven without rebuying the platform.
Modular tables, oven covers, and Ooni’s Connect Digital Temperature Hub are all 20 percent off. The Modular Table at $260 is the cheapest way to get a Koda or Karu off the patio table and onto a permanent setup, and the infrared thermometer at $52 is the single most useful $50 you can spend on pizza, since stone temperature determines whether your crust leopards or burns.
All three Ooni-branded cookbooks are 20 percent off, with Pizza Czar by Anthony Falco at $28 being the one to buy if you want recipes from a real consultant who’s helped open pizzerias from Brooklyn to Bangkok rather than just Ooni’s house style.

Smart lighting manufacturer Govee is apologizing after a pair of books showing only the words “white supremacy” were featured in a marketing image on its website.
The books were visible in an image (shown above) on Govee’s US website for bedroom lighting. Disturbingly, the books sat under toy animals on a shelf just above a child’s bed. Only the books’ spines were visible.
The Verge was the first to report on the controversy after a reader contacted the publication. The publication reported that it contacted Govee, which subsequently removed the image but didn’t respond to the site's queries before it published its initial report.

AcuRite must kill its customers’ favorite companion app due to “obsolete technology," VP of product development Jeff Bovee tells Ars Technica.
AcuRite, which makes smart weather-monitoring devices, announced this month that the My AcuRite iOS and Android app that has been around since 2016 won’t be available after May 30. After that date, device owners must use AcuRite NOW, which AcuRite released in June 2025, to control their gadgets.
The announcement has frustrated long-time AcuRite users, largely because the new app lacks some of its predecessors' capabilities. For example, AcuRite NOW doesn’t allow renaming multiple temperature sensors, organizing on-screen sensors, or reporting temperatures as anything other than whole numbers (AcuRite says it's working on adding some of these features).
