Best Prime Day deals under $50

One of our favorite teeth-whitening strips, these are coated in a layer of hydrogen peroxide to remove stains. Plus, they’re flexible and easily mold to your teeth. There are 22 treatments in the box: 20 are 45-minute standard treatments and two are 60-minute express treatments.

You’ll find an Owala reusable water bottle and tumbler on each of our editors’ desks, both of which are on sale for Prime Day. “I love the look and shape of my Owala tumbler — I prefer a side handle over one on top. The handle is incredibly comfortable and the bottle itself doesn’t feel super heavy and doesn’t make a ton of noise when I accidentally hit it against something,” says NBC Select commerce editor Cory Fernandez. “It’s also easy to clean, including the lid and straw. Plus, it keeps my iced drinks cold all day when I’m at work.” According to the brand, the bottle’s dual-wall insulation helps keep drinks cold for up to 24 hours at a time.

The Echo Dot is a speaker, temperature sensor, home theater system and Wi-Fi extender all in one. The device can also stream music, podcasts and audiobooks, and it’s compatible with Amazon Alexa, so you can set timers, get weather updates and more using voice commands.

This anti-frizz spray helps minimize heat damage and leaves hair looking glossy and smooth after styling, according to the brand. I use this product regularly before styling my hair because it doesn’t weigh down my hair and smells great. The brand recommends evenly distributing the product through damp hair and blow drying afterward.

This viral tumbler is a favorite among our editors, and for good reason: Its stainless steel interior keeps drinks cold for hours (I’ll even have unmelted ice in my water more than two hours after I poured it). The tumbler is also compatible with most cup holders, like the ones in your car or on the treadmill. Only select colors are on sale for Prime Day.

Make smoothies and juices from anywhere using this portable blender, which holds up to 18 ounces of your favorite blends. The base is rechargeable and you can sip from the lid, so you don’t have to pour it in a separate container. It’s also top-rack dishwasher-safe and fits in a car cup holder.

This battery-powered Ring camera lets you see, hear and talk to visitors directly from your smartphone or tablet. It has motion detection, color night vision and two-way talk, plus you can view a live feed and change your settings in the Ring app. The camera can stand on its own, or you can mount it on your wall.

This tinted sunscreen is one of our favorites for darker skin tones. It has iron oxides, which are mineral pigments that create tint, and titanium dioxide to protect your skin from the sun’s harsh rays, according to the brand. It also has vitamin E to keep your skin hydrated and dimethicone, an emollient that helps your skin retain water.

This personal filter gets rid of parasites, microplastics and other impurities from your water as you sip through the mouthpiece. The slim, lightweight shape is also travel-friendly for outdoor adventures like hikes and camping trips.

You can mix this collagen powder into both hot and cold beverages, including water, smoothies, coffee and tea. It has collagen sourced from grass-fed, pasture-raised bovine, vitamin C and hyaluronic acid to keep bones, joints, nails and hair healthy, according to the brand.

This portable Bluetooth speaker is a must for summer — you can throw it in your backpack or tote bag for your trips to the beach or to sit by the pool. It’s water-resistant and has up to five hours of playtime on a single charge.

If you have fine hair, making sure it doesn’t fall flat can be a daily struggle. This shampoo has a blend of biotin and collagen, which helps hair look thicker and boosts volume. It also has fragrance notes of coconut, jasmine and lemon, so your hair will smell good hours after your shower.
