15 best Prime Day deals under $50, like JBL earbuds for a record-low 55% off

If your less-than-glowing chompers could use some restoration, the folks at Crest say these bestselling strips can make teeth up to 20 shades whiter in just 22 days (that's almost one shade per day!). According to the brand, you're guaranteed to have a noticeably whiter smile, and with this kit, you'll get some bonus express treatments for same-day results. Now say "cheese!"

"I’m 64. I wanted to look good for my daughter’s wedding, yet my teeth were literally yellow ... a few were almost brown," shared a convert. "I’d tried white strips in the past (when they first came out) and they didn’t help at all, so I didn’t think they would help now. My dentist and my daughter told me to try them again anyway. Discouraged, I decided to try them out about a week before the wedding. Amazingly, my teeth turned from yellow/brown to almost white before the rehearsal dinner. I’d say if you were on the fence, buy these!"

These No. 1 bestselling pillows are hits among hundreds of thousands of Amazon shoppers (really) and Yahoo readers can't stop scooping them up, either. They're made of a cooling gel to help keep those uncomfortable night sweats at bay, and the plush Oeko-Tex Standard certified material will feel like heaven while you sleep. 

They're not often on sale for 40% off unless it's for a big event like Prime Day.

"They don't get flat or bunch up," noted a shopper. "They are thick and fluffy. I get a great night's sleep on them. They are also cooling, so I don't wake up hot anymore. Well worth purchasing, and has improved my quality of life with better sleep."

Want to streamline your streaming experience? This Roku stick will have you flipping through Netflix, Disney+, Hulu and more, seamlessly. With 4K resolution and Dolby Vision, your viewing experience will be a crisp, vivid one, and it's compatible with voice-control programs like Siri and Alexa. It's rarely on sale for less than this, folks. 

"This stick is inexpensive enough to use with a not-too-smart TV to get a taste of streaming services," wrote one shopper. "It's also handy to have when weather and/or tree foliage blocks the satellite dish. It plugs directly into an HDMI port and is powered by the set's USB, so no other cables/power packs are needed."

Want the wireless earbud experience without the high price tag that comes with AirPods? This pair has over 12,000 perfect ratings and boasts strong bass, noise cancellation (along with a setting that lets you stay aware of your surroundings), four mics for hands-free calling and up to 40 hours of battery life. Oh, and these bad boys are water-resistant and sweatproof, making them ideal for your gym workout. Most exciting? They're down to the lowest price we've ever seen. 

"I love them," raved a fan. "The battery life goes above and beyond, the quality of the sound is perfect, they are super comfortable while working out or lying down and I love the controls. This is actually the second time I've bought these. I had the first pair for a year before losing them on a trip. After that I tried more than a few other brands ... and those just didn't measure [up]."

This oral hygiene essential is actually on sale for $49.99 — just made it ... and we'll take it! With this, your dentist won't ask if you floss, but how you floss, because they'll be so impressed by the lack of residue surrounding your teeth and gums. And you'll be pleased too, since this device feels much gentler than cramming a piece of string between your pearly whites. It comes with seven tips so the whole family can use it. Another reason to smile? We haven't seen it on sale for this price since Black Friday.

"Cleans like a champ," said an impressed user. "Waited way too long to get one of these, but it was sure worth buying. Gets in between teeth perfectly with no pain. Amazed at how much is still between your teeth after [conventional] flossing. This makes short work of anything left. Great buy."

You can't really put a price on having real peace of mind ... but we'll take 50% off!

It's easy to set up (mounting hardware is included) and connect to Wi-Fi via the Ring app, so your home will feel more secure in a jiffy. Oh, and now you'll be able to see when all of your Amazon goodies arrive. 

"The Ring Video Doorbell has been a fantastic addition to my home security setup," shared a buyer. "Installation was straightforward, and the video quality is excellent, both day and night. The motion detection is highly sensitive and sends alerts instantly to my phone, which is great for peace of mind. The two-way audio feature is very handy for communicating with visitors without opening the door. Highly recommended for anyone looking to enhance their home security!"

Tens of thousands of Amazon shoppers have experienced impressive results with this top-rated serum, which contains vitamins, peptides and amino acids to help thinning lashes appear fuller and longer. Just apply once daily, and you could see improvement in as little as four weeks, with the full effects kicking in after about three months, according to the brand. We haven't seen it dip lower than its current price in years. 

"It works!" decreed this satisfied shopper. "After using this product for years, I thought that maybe I could get along without it; however, after trying to apply mascara to stubby, sparse eyelashes, I quickly purchased it again. At an advanced age, there isn't much left to work with, so I'm not giving up the one product that puts 'life' back into my eyes!"

Stiff mattress? Give it a little facelift courtesy of Amazon's No. 1 bestselling sleep surface. Made of gel-infused memory foam, this was designed to conform to your body's shape for customized support, helping to alleviate stress on pressure points. The gel it's infused with is described as being "cooling," as it's meant to draw heat away from your body, and as far as quality is concerned, you can rest assured — pun intended — that this topper is CertiPUR-US-certified. Plus, it comes with a three-year limited warranty, and this is the lowest it's ever been marked down to. 

"I like sleeping on firm beds, but unfortunately my bed was a little too firm," explained one (now) satisfied sleeper. "It was causing upper and lower back soreness and sciatica. I was really skeptical that this would help ... because sleeping on soft surfaces gives me lower back and hip pain. This was a lifesaver, though. It provides just the right amount of cushion for me to be supported on my firm bed. I've had it for around six months and I am still loving it."

Everyone's favorite baseball-sized smart assistant is back on sale for an eye-opening 50% off — bringing it just $2 shy of its all-time lowest price. One of the most powerful Dots yet, it has built-in temperature and motion sensors to set up useful routines. You can pair multiple devices together to expand the functionality across the home. Worried about privacy? An off switch makes it easy to disable the mic when you want to be sure it isn't listening. 

"I purchased this to help a family member who is older and needs help with things," shared a shopper. "It's great for turning off the lights, asking what the weather is today and to keep track of their calendar. Also, if they slip and fall they can use Alexa to call for help. Sound quality is pretty great for the size."

Cleaning your floor can be, dare we say, fun? Yes! At least, it is when you have this No. 1 bestselling mop set in your arsenal. The included bucket has a built-in wringing system so you don't have to use your hands — just place the mop in, press the pedal with your foot and it'll start spinning itself. Plus, the triangular head is helpful for getting into corners, and the handle extends out to 48 inches in case you want to wipe down your walls while you're at it. It's not often on sale for this low, so snag it while it's $10 off. 

"This is the easiest and cleanest way to mop!" swooned a content customer. "Absolutely love it, if you can actually love a mop, LOL. ... I've mopped with it approximately 6-7 times and am still using [the] original mop head."

If you're on social media, you may have seen this viral yellow tub in many a skin-care video. Formulated with cupuaçu butter, açaí oil and coconut oil, as well as caffeine-packed guaraná, it delivers essential hydration while helping smooth skin and making it feel firmer. It also smells divine, with aromas of vanilla, salted caramel and pistachio. 

It's not the biggest Prime Day discount, but this No. 1 bestseller rarely goes on sale, and our price trackers tell us this is as low as it's been in years. 

"Heaven in a jar," gushed a reviewer. "I’m totally hooked on this body cream. At 56, I’ve never used anything that not only tightens, but makes my skin feel incredibly soft and smell so yummy as Bum Bum does … and it doesn’t take much. A little goes a long way. Bravo!"

According to our price trackers, this is close to as low as this No. 1 bestselling hand vac gets. It weighs just 2.6 pounds, so your arms won't resent you once you're finished cleaning, and it's got a built-in crevice tool for reaching those itty-bitty spaces. The rotating nozzle helps you reach odd angles, and its flip-up brush is handy for cleaning furniture and upholstery. 

"I am a newer German Shepard owner and let me tell you, I was NOT prepared for the hair," confessed a pet parent. "Even after regular brushing, it’s everywhere. Well, this little vacuum has made my life easier. As for performance, it’s still going strong after a few months of daily use. The attachments are great at getting places I can’t with a big vacuum; it’s the perfect size — even my little one can help and it cleans out easily. It doesn’t take long to charge."

Enjoying a warm breakfast on a busy morning has never been so easy, thanks to this contraption that'll make a bacon, egg and cheese (or two) without you having to wait at the drive-through. Just fill each tray with your bread, eggs, cheese and any toppings you'd like, and it'll cook everything so that it's nice and melty by the time you've gotten dressed. 

We haven't seen it on sale for this low since 2021, and it hasn't dipped lower since 2020, making this one of the best Prime Day kitchen deals so far.

"Trust me when I say, it's a game-changer for breakfast lovers everywhere," raved one happy home cook. "Not only is it super easy to use (just pop in your ingredients, close the lid, and voila!), but it's also incredibly easy to clean. No more messy stovetops or multiple pans needed — just one compact device that does it all."

There's a better way to get rid of pesky pests than by swatting them — this device lures bugs into its sticky traps via UV light. So long, fruit flies! By applying Yahoo's exclusive code 20JULYKATCH, you'll save over 50% — its lowest price year to date. 

"This has proven to be extremely effective and very easy to maintain and clean," buzzed a fan. "Quick-access sticky pad door makes swapping out the insert an effort of mere seconds. The best thing about it is that they actually work. Sure, they take time, but after a few days you'll be amazed at how many bugs you'll catch. Funny how you never really see all of the flying insects that infiltrate your home, but ultimately this gets them."

Spare yourself a trip to the salon and give your hair a sleek blowout via this No. 1 bestselling hot air brush. Now you can style while you dry, which saves precious time on hectic mornings. Whether you want to straighten and smooth your hair, add some waves or just amp up the volume, this multitasker does it all — and it's on sale for just about as low as it's ever been this year.

"I am 60 years old, I have never in my entire life been able to do anything with my straight-on-top, curly-on-the-bottom, thinning hair," shared a reviewer. "Well, after buying every tool and styling gadget on the market, I gave this dryer brush a try. It’s a miracle; my first try, and I have a salon style from my own bathroom! It’s so full and healthy-looking and pretty, and I feel so amazing personally! It’s not at all heavy; it is noisy, but it is just an amazing thing."
