We only recommend products we love and that we think you will, too. We may receive a portion of sales from products purchased from this article, which was written by our Commerce team.

Some things have always been destined to become popular, like butterfly clips in the '90s, or — for a more recent example — air fryers and Instant Pots in the past couple years. I still don’t completely know why we all want certain items at the exact same time, but to keep you up to date on the latest, here's a list of trending things that are so hot, Amazon can barely keep them in stock.

There's a reason Amazon has a “Buy Now” button on every product page: The site constantly sells out of some products every time they hit the shelves. To keep an eye on things, I pay attention to products with reviewers who say they are “obsessed” or have been “waiting for this one to come back in stock." High star ratings are another good way to tell if something is destined to become the next big thing you won't be able to find anywhere, like this compact air fryer that sells out time and again, or this smart water bottle with a cool three-in-one design (it doubles as a Bluetooth speaker and also glows on the hour to remind you to hydrate). Just for you, I’ve rounded up some of the hottest products on Amazon today — many of which just might be gone by tomorrow.


The privacy phone screen protectors that keep out prying eyes

Keep your phone screen protected from damage — and potential prying eyes — with these privacy screen protectors. They make it impossible to view your phone screen from the sides, and the ultra-thin tempered glass defends against scratches without impeding on touch screen sensitivity. You get two protectors in the pack, so you can also protect your partner's device. So many reviewers have rated it "perfect."


These wireless earbuds that come with a charging case

Eliminate the tangle of cables when listening to playlists on your phone with these true wireless in-ear earbuds. They're water-resistant to stand up to sweat and rain, and the included charging case means you get 24 hours of battery life. Plus, they boast three EQ modes, so you get an ideal audio experience, whether you're listening to music, watching a movie, or catching up on your favorite podcast.


A 7-in-1 trimmer for *all* the hair

One reviewer called this seven-in-one shaver an "excellent value for the money," and I couldn't agree more. After all, the compact tool can cut hair, shave, trim nose hair, tidy up sideburns, cleanse your face, and even dry brush, thanks to the seven smart attachments that make it all possible. This shaver is waterproof for use in or out of the shower. Now, that's hot.


A FIDO security key that keeps all your information secure

Keep your online accounts and files protected with this NFC security key. Offering two-factor authentication alongside your account passwords, this simple device works with your existing USB port. It's compatible with Chrome, Windows, MacOS, and Linux for wide-ranging password protection against phishing attempts.


A digital notebook you can use again & again

Take notes, save them to the cloud, and then begin again with this smart notebook. Ideal for those who love to write on paper but hate the clutter of multiple notebooks, this standard-size book works with a compatible app to quickly save everything you write on your preferred cloud service. Then, when you're done, simply pop it in the microwave (really) to wipe the pages clean.


This Bluetooth water bottle that reminds you when to hydrate

Get a gentle glowing reminder to take a sip of water on the hour, every hour with this fun three-in-one water bottle that also doubles as a wireless Bluetooth speaker. In fact, the lights can even sync to your playlist, creating a portable party anywhere you go. Set the bottle on a wooden table (after you drink, of course) for truly resonant bass.


This electronic lock for cabinets

Turn a cabinet into a storage locker with this nearly invisible cabinet lock. It can be installed without a ton of tools and works with the included programmable key cards and fobs to provide quick access to your stuff — while keeping other people out. This lock even comes with a USB cable to charge the lock if you don’t have batteries on hand.


This smart toothbrush that rewards you for proper brushing technique

Rewards? Just for brushing my teeth? Count me in. This smart toothbrush kit connects to an app that helps guide you on proper brushing techniques, and as you improve (and brush regularly), you'll earn rewards like free trials for the Headspace meditation app. It comes with two brush heads (Alexa can remind you when it's time to order more) and a travel case. This Amazon exclusive is jumping off the shelves, so grab it fast.


A clever flask that masquerades as an umbrella

Bring your refreshment along to the party with this clever umbrella flask. An ideal gag gift, this plastic bottle is designed to look just like an umbrella, right down to the wristlet carrying strap. This flask even comes with a pouring spout to easily fill your glass.

Two holes match a range of door types, and it's a breeze to install by sliding it over the latching mechanism, closing the door, and hanging the red handle on the metal plate. Super easy.


This window privacy film that still lets the light shine in

Letting a little natural light in can really enhance your space, but you often have to sacrifice some privacy.

A 5-stage filtering pitcher with a water quality meter

A key-size multitool that performs 16 functions

Clip this key-shaped multitool to your key ring, and you've got a gadget to meet virtually every need. This handy tool can drive in screws, attach bolts, take measurements, and even strip wires. When you're done fixing, use the bottle opener to enjoy a drink of your choice. You've earned it.


A cold brew coffee maker with an airtight construction

A 4.6-star overall rating means you can't possibly go wrong on this cold brew coffee maker that makes it "very easy to make cold brew," as one reviewer shared.

This compact air fryer that supports healthier snacking

Enjoy your favorite fried snacks with a lot less oil when you have this compact air fryer on hand. The 2-quart size is ideal for smaller kitchens, where it whips up batches of fries, coconut shrimp, wings, and more — with little to no oil needed. In fact, the nonstick basket construction means you don't even need cooking spray.


This retro-inspired essential oil diffuser

The 4-in-1 wireless charging station for all your devices

There are a lot of charging stations on the market, but there aren't a lot that easily handle your phone, smart watch, earbuds, and (wait for it) digital stylus all in one place. This compact four-in-one charging stand has a small footprint that fits on your nightstand or desk and provides dedicated space to stow and power all your devices at once.

A perfect companion for your afternoon stroll, outdoor baseball game, or planned vacation to a warm-weather destination, this bladeless neck fan offers quiet comfort to beat the heat. This fan uses turbine blade technology for super quiet cooling power on three speeds, and the silicone construction is gentle on your neck for easy wear.


A mini waffle maker that's ideal for single servings

This waffle maker is the cutest thing I'm going to share with you today. (I mean, just look at it.) The small size is ideal for apartment or dorm life, serving up one perfectly made waffle, chaffle, or even a serving of hash browns in just a couple of minutes. A bunch of color and pattern options (think: white pineapples, skulls, and leopard print) just add to its quirky charm.


A microwaveable popcorn maker that doesn't need oil

Make movie theater-quality popcorn at home with this popcorn popper that works with your microwave and doesn't require oil.

Available in an array of colors, the 3-quart size is perfect for sharing with friends or family, but you can also opt for a personal snack-size popper.


This moldable glue for fixes & crafting

Whether you're crafty or clumsy — I confess to being the latter — this colorful multipurpose glue provides a perfect solution. Mold it with your hands to repair floppy shoe soles, wrap it around frayed wires to restore your connections, or use it for brand new artistic creations, like hooks for your coffee mugs. The options truly go on and on.


This 4-outlet splitter that increases plug-in space

Extend the function of a basic home outlet with this four-outlet splitter. It takes up just one AC outlet, yet offers four extra connections for appliances and three USB ports to charge multiple phones or other smart devices. Best of all, it doesn't get in the way of the outlet above it.

This magnetic screen door that lets the breeze in & keeps the bugs out

The rattle and bang of a screen door is really annoying, but it does a great job of keeping the bugs from invading your home. What to do? Install this magnetic mesh door instead.
