A bunch of the best products we've ever tested are on sale for Black Friday

Our favorite electric toothbrush is practically at stocking stuffer-level price this Black Friday. And not only is it affordable, but it also won out in our testing. Editor Rebecca Carhart says this Aquasonic model "leaves my mouth feeling extra clean every time I use it." What more can you ask for from a toothbrush?

Give the gift of better sleep this holiday season, with the winner of our best sleep tracker testing. The Oura Ring Gen3 Horizon was "like having a sleep coach on your finger," and it won handily against the competition. Get one now for $50 off.

Any home gym worth its weight (barbell?) needs a good resistance band. We tested more than a dozen to find the best of the best, eventually crowning this Living Fit 8-piece set the winner. You'll get two bands in four sizes (two of each size), each with a different resistance level. Our tester loved how durable they were — and we don't hate the lifetime warranty, either.

The jetsetting Yahoo editorial team loves this bag for its anti-theft capabilities, like RFID-blocking pockets and lockable zippers. If you've got any trips planned for the new year, you could do worse than this versatile cross-body bag, our overall top pick for best travel purses. And yes, it's on sale.

I once dropped off my checked luggage with a TSA agent only to watch them toss it onto a pile of other bags and yell "Opa!" Since then, I've gotten a lot more interested in hard-side luggage. And of all the options we've tested, this one from Delsey Paris came out on top — the top of the TSA heap, sure, but also the top of our list. We love that it's expandable, lightweight, super-roomy and even kind of chic. We recommend grabbing one while it's on sale.

Sure, warm socks are great, but have you ever tried heated socks? Style Editor Rebecca Carhart sure has. After testing all the top options, Carhart found a clear winner in this Savior pair, which fit easily inside boots, heated up quickly, and warmed her toes even when not turned on. Don’t get cold feet, because this Black Friday deal isn’t going to last forever.

Once you've cooked with a good chef's knife, you'll never go back to a sub-par blade. Home Editor Lisa Schweitzer called this winning slicer the Goldilocks of the category, saying it made everything she cut feel "as soft as Marshmallow Fluff." One thing she didn't love was the price, but this Black Friday deal completely chops up that criticism.

What if we told you the best pizza oven we've ever tested could be yours for $100 off during this Black Friday sale? The moon hit our eye like a big pizza oven when we tested this Gozney model, which we loved for its protective coating, minimal setup and that you can use it for more than just pizza. We think this year might be the year you finally become a pizzaiolo.

Our pick for best cookware set is already pretty affordable for how great it is. But the value's even higher this Black Friday, with a 30% discount. We love that these pots and pans can go from stove to oven, and Schweitzer said that during testing, her scrambled eggs "slid right out of the pan and left no residue."

There was a clear winner when Schweitzer did her testing to find the best Dutch oven. This Le Creuset beauty stands the test of time. Schweitzer has been using hers for almost twenty years and says it still works as well as it did on day one. She calls the price "an investment," but slightly less so during this sale.

Our veins are like 50% coffee at this point in the year, so we're big fans of the single-serve coffee maker. The best Keurig machine, according to Senior Home and Garden Editor Jessica Dodell-Feder, is the K-Café Barista Bar, which is currently on sale for 30% off. That's only a few bucks over its lowest price of the year. Dodell-Feder loves this coffee maker for its ease of use, its "over ice" option, and its included milk frother.

More of a Nespresso person? Our favorite of all the Nespresso machines we tested is also on sale for Black Friday. Dodell-Feder says this nifty one-button machine made her mornings “about a million times better.” Not only does this pod coffee maker take the guesswork out of brewing your daily dose of caffeine, it also throws your used pods away for you. Oh, and it's on sale.

We don't discriminate between single-serve and drip coffee makers (or espresso machines, or iced coffee makers, for that matter) — we'll take the caffeine however we can get it these days. And our budget pick for best drip coffee maker, the Cuisinart 14-Cup Coffee Maker, is even more budget-friendly during its Black Friday sale. This slim-profile machine comes with lots of programming options for coffee geeks, and its reusable gold-tone filter is both environmentally friendly and makes for a more flavorful cuppa joe.

You know what they say: Two monitors are better than one. Yep, even if you're on the go. Our budget pick for best portable monitor after extensive testing was this one from MNN, which you can get for even less right now. Other portable monitors we tried are priced in the several-hundred-dollar range, so this really is a steal.

If you've ever wished your TV looked more like a piece of art when you weren't watching anything, one of our picks for the best art TVs could be a great option for you. Veteran Tech Editor Rick Broida's favorite is The Frame from Samsung, which "easily bests" the competition, and it's on sale for Black Friday

The verdict is in, and the best streaming device overall is the Roku Ultra. Broida, who "watches an embarrassing amount of TV" (his words!), prizes its clean interface and simplicity of use. It's also got a great voice remote and delivers a crisp picture. Best of all, it's on sale for Black Friday.

You could say we have strong opinions about speakers, but we prefer to call ourselves audiophiles. Broida picked the Tribit StormBox for best outdoor speaker after extensive testing, citing its big, bright sound and extra-long battery life (up to 30 hours!). We know from experience that this speaker doesn’t go on sale very often, so we recommend you pounce on this all-time low price.

A sale on these wireless earbuds, our fave budget pick in the category, is just music to our ears. And right now, you can get a pair at their lowest price ever. Broida, who is our resident tech editor and a certified music snob, marveled at these affordable buds when he tested them. "How can $40 earbuds possibly be this good?” he asked. But he’s going to have to change his tune during this Black Friday sale: How can $25 earbuds possibly be this good?
