You’re about to see a whole lot of this viral $18 knife set and reviewer-beloved scalp renewal brush.

As a Senior Shopping Writer at BuzzFeed, I specialize in a broad range of topics, including beauty, cleaning, fashion, personal care, home, fitness, and my beloved “TikTok made me buy it.” My work has been featured across lifestyle and writing publications during my ten years in the digital media space, including Bustle, HuffPost, HelloGiggles, and The Washington Post.

Promising review: "Love this product! I work out on the go, so I’m always in need of a water bottle, but I hate carrying a big one around all the time. This bottle is a nice size to use while running/walking (lightweight and easy to carry), it doesn’t leak like most plastic bottles, and it’s easy to roll/fold up and store in a bag after you’re done. Overall, great design and functionality. 10/10." —LaMonica

Get it from Amazon for $17.99+ (available in five colors). 

Promising review: "First off, if you have extremely oily skin, this. is. it. I was so tired of getting blotting powder/wipes. It felt wasteful and always left residue on my face. I saw this on TikTok and NEEDED it. It was backordered but then I got an email saying it was in stock and I was SO excited. Not only is it affordable, but it's washable, which helps you save money and be less wasteful." —Kelsey B.

Promising reviews: "Attractive, handy, reasonably priced knife set. I’ve been using these knives for several months and find them to be sharp and rust-free. Also, the kitchen shears are handy and well-made. The set covers every knife I use regularly, and they’re comfortable to use. Highly recommend! 🌟🌟🌟🌟🌟" —Jeamss

Get it from Amazon for $17.96+ (also available in two other on-sale color palettes). 

Promising review: "The texture is thick! But it’s a good thick. These feel so smooth on the lips and are very glossy. Currently my favorite E.l.f. lip product, over the Glow Reviver Oil. Smell is not overwhelming and neither is taste. I came back to order them all." —Khloe3

Promising review: "Game changer after wearing earbuds for years and suffering very uncomfortable pain inside my ear from the hard plastic contact, one to two hours max!!!! I now wear these ALL day with no discomfort and the ability to hear my surroundings :). Also helped with my level 10 tinnitus!!!! Well-made, lightweight, all-day comfort, great battery life, and easy Bluetooth connectivity. 10/10!!!!" —Scott Garrard 

Get it from Amazon for $99.95 (available in two sizes and two colors). 

Megababe is a small business that specializes in body care. 

Promising review: "Megababe Thigh Rescue has been a total game changer for me. It goes on clear and never feels greasy or sticky. If anything, it is moisturizing. The chafe protection lasts up to 12 hours, which is a huge win. I use it on my thighs, my waistband, and anywhere my skin tends to rub together. The quality is great, and it smells wonderful without being overwhelming. As a bigger girl, this is essential for me, especially in the summer. It works perfectly with dresses, shorter shorts, and anything that might cause rubbing. This is 100 percent a necessity in my routine." —Stephanie

Psst — BuzzFeeder Elizabeth Lilly has tried the newer Megababe anti-chafing gel, and is already a fan! 

Promising review: "I was not expecting this brush to be so amazing. I usually use a Wet Brush, and NO MORE of that. This one doesn't pull when the Wet Brush did. Feels amazing on my scalp. Just a very refreshing brush to find. I would definitely recommend this to everybody that has a hard time brushing their hair (even kids), very soft, and the price is excellent as well. Love love love this brush. Would definitely buy again and again." —Katy Shoemaker

Promising review: "This stuff is AMAZING! I love the larger roller ball, the cooling effect, and the instant depuffing of my eyes. Will definitely keep on hand!" —TRISTA T. 

Get it from Amazon for $10.10+ (available in a steel or rose quartz rollerball). 

Promising review: "This product, my drill, and the flat sponge type cleaning pad were the only thing that worked transforming this very dirty tub into cleaner than clean. Very little muscle power necessary. A little goes a long way. It takes off the worst of things and leaves a kind of ceramic coat behind. It’s amazing." —Glinda

Touchland is a small business that specializes in hand sanitizers. Check out a TikTok of the Disney x Touchland Power Mist in action. 

Promising review: "The perfect accessory for my last Disney trip. Not only is it adorable and add a bit of that Mickey flair, it is reusable (so I can just pop in another one of my favorite Touchland hand sanitizers), the initial spray is delightful and fresh, and the little key ring allows me to attach it right to my park bag, providing a simple ease and access to spray our hands after each ride around the parks. Super cute and highly recommended!" —Shelby Piper

Get it from Amazon for $20 (and check out Touchland's Amazon storefront for more options). 

Promising review: "Great little pouches to help organize your purse or backpack. I use it for my makeup and a separate one for essentials while I am out and about. I love that I can see what’s in them instead of having to rummage around. Haven’t had to clean them yet, but that seems like it will also be very easy to do." —KR

Get it from Amazon for $8.99+ (available in 12 styles). 

Promising review: "This is the best knock-off Scrub Daddy/Mommy. It cleans just like the original, doesn't scratch your pans, and gets all the grease and baked-on dirt that’s left on your plates, pots, or pans. Works well and activates to soft when under hot water or hard when under cold water. Easy to use and doesn’t smell. Rinses the food or grease off with no problem. Hopefully, they do not go up in price. I received three cute smiley face sponges that have eyebrows, so they would definitely fit on your Scrub Daddy suction cup if you have one. This is now my go-to sponge for dishes, bathroom cleaning, and my baseboards." —Deeva

Get a set of three from Amazon for $8.99+ (available in eight styles). 

Promising review: "I bought this to wash baby bottles and pump supplies. Good build and does not feel cheap. I like that it is collapsible for storage and it has a drain on the bottom which makes it super convenient to drain after a soak. I can fit a lot in the tub for soaking." —Lacey D. 

Promising review: "Just the right size for grabbing things out of my toaster oven and microwave. Easy to hold onto handles and without handles. Not too thick, but I felt no heat, easy to wash off, good value, and quality item. Wish I’d bought sooner." —Bonny Anne

Get it from Amazon for $12.99 (available in six styles). 

Promising review: "Love these! Very comfortable to wear all day long. They don't keep their head away from the headrest when driving, which is incredibly important. I even wore one underneath a hat to a dress-up function and was still comfortable. The clip spring is strong and holds even my very long, thin, fine, and straight hair — no pulling, a few hairs, and very little slipping down even after hours of wear. They don't hang up in your hair like some metal ones do. These are the best hair holders I've ever bought, bar none." —Paint Mare

Psst — parents really love this as a "calm down" moment for their kiddos! 

Promising review: "This little cloud guy is adorable and squishy! His face is very sweet, and the color morphing is great. I really like it’s calming, and even if you don’t use it for meditation, it’s a cute night light." —RgHound

Promising review: "This air fryer guide is so useful that I purchased several for family members. They really like it too. It has all you need to make air-fried foods a success. It is easy to read and understand. I like that you can wipe it off. It stores conveniently on my refrigerator by the magnet on the back." —Spindoc16

Get it from Amazon for $8.87 (also available in Instant Pot and keto-friendly versions). 

Promising review: "I didn't know it was possible to fall in love with something simple like this, but here I am doing it. It's just so cute for a nighttime routine, and I love the wrist guards that keep the water from running down my forearms when I wash my face. I think it's nice to feel all pretty as you crawl into bed, and this helps, plus it's functional." —Amy Lataur

Get it from Amazon for $8.98+ (available in DOZENS of styles). 

Fullstar is a small business established in 2017 that specializes in kitchen gadgets. 

Check out a TikTok of the veggie chopper in action. 

Promising review: "Makes life so much easier. I can't imagine chopping onions or bell peppers by hand anymore, and it does so much more. We used to have a Prepworks chopper, which was a similar idea, but you had to press so hard to chop, and it broke after not too long. This one requires very little effort to cut through the food and it has a generous container." —Amazon Customer

Get it from Amazon for $23.73+ (clip the coupon on the product page for this price; available in four styles and in four colors). 

Promising review: "These earplugs are so good!! I had originally bought a completely different brand (because I was being cheap), and let me tell you, you get what you pay for. I found these Loop earplugs and decided to give them a try, and I’m so glad that I did! They are so comfortable! Made from silicone, so they are flexible and fit great. I’ve slept with them in all night without issues. The noise canceling is fantastic! Now, does it block everything? No, but I think that’s a good thing for safety reasons. They do block my husband’s chainsaw snoring, and that is exactly what I needed them to do." —melanie98837

Get it from Amazon for $24.95 (available in seven colors; check out Loop's Amazon Storefront for more options related to concerts, offices, and parenting)!

Febu is a small business that specializes in earth-friendly, non-toxic home products. 

Promising review: "I love these! I have used these for years instead of a sponge or a dishrag. They hold up great, mop up crumbs and spills quickly, can be popped in the dishwasher to clean, and bring a bit of color to the sink area in my otherwise neutral kitchen." —Wynnefred

Get a set of five from Amazon for $14.95 (available in 15 very pretty sets). 

Cup Cozy Pillow is a small business that specializes in family-friendly snack and drink organizers. 

Check out a TikTok of the Cup Cozy Deluxe Pillow in action.

Promising review: "This thing is great! I’m home on maternity leave with my new baby and spend most of my time on the couch under a sleeping baby. This product makes it easy for me to keep my drinks, remote, etc close by even with dogs running around. It’s a little more expensive than I would have liked but it works and I love it so money well spent!" —Amber

Get it from Amazon for $34.99 (available in nine patterns). 

Promising review: "YESS. I LOVE this towel. It's warm, big, soft, and cozy. Great for the price. I got the light pink color, and it's very cute. I love the side pocket so I can put my phone there when walking from the bathroom to my room. It's very long as well, and goes down below my knees. Quality is great, the Velcro and button have never caused it to fall down or off of me." —Alyssa Grabowski

Get it from Amazon for $14.99 (available in 16 colors and sizes S–3X). 

Promising review: "These are the best for half of any round fruit or vegetable. I'm loving them and [that there's] no more messing around with so many small plastic bags. They don't seem to pick up the smell of onions either, which is a big plus! Easy to open and close, keep food fresh, and seem to be durable. I've had them for a few months now and I'm going to give some away as gifts to family and friends!" —Amazon Customer 

Get it from Amazon for $13.99 (available in two colors).

Check out a TikTok of the Prepara Salad Pod in action. 

Promising review: "An awesome invention. I take salads daily to work, and it’s so convenient. Also the dressing at the top makes mixing salad so easy." —Adrienne Williams 

Check out a TikTok of the condiment fork in action. 

Promising review: "Great kitchen item. Forks are great to get pickles out of the jar, but if you have kids/lazy people (lol), you know that dirty hands are going into that jar. 😉 This has really prevented that from happening. It comes with two different rings to fit whatever size jar, a stabber holder, and a stabbing stick." —Amazon Customer

Promising review: "I didn’t understand how this tool was going to work, but I saw a TikTok where someone used it as part of their everyday cleaning routine, and my curiosity got the best of me! And wow, oh wow, am I glad I did! The area has to be big enough to pull it back and forth, so it’s ideal for couches and beds, and other furniture. It is so easy to empty too, and oh so satisfying to see what you picked up with it! Now I want to try the handheld version for clothing!" —Kindle Customer

Hover Cover is a small business that specializes in microwave covers for home kitchen use. 

Check out a TikTok of the microwave cover in action. 

Promising review: "If you live in a small space like I do, this will seriously change your life. No longer do I have to struggle to find somewhere to put my cover if I'm heating up a cup of coffee. Just attach it to the roof of your microwave. Hopefully, you have a flat surface; check before you buy. There is a slight learning curve as to where to put it or the force or lack thereof needed, but after a couple of times, it's second nature. Love, love, love this product. I'm probably going to get some for Christmas presents next year, it's one of those items that you wouldn't necessarily buy for yourself, but it will change your life." —Rachel

Get it from Amazon for $19.95 (also available in two-packs).

Check out a TikTok of the oil sprayer in action. 

Promising review: "I really like this sprayer. The glass bottle gives it a slightly heftier weight than the all-plastic variety, holds a lot of oil, and has an awesome spray pattern (sprays evenly every time). It's also pretty. The gold design on the bottle gives it a more luxurious look. Fits my hand well, and easy to use. Would recommend." —Norma P. 

Get it from Amazon for $24.99 ( available in three styles). 

Check out a TikTok of the cloud knife in action. 

Promising review: "I love these — sturdy, sharp with retractable blade. I keep them in different rooms for opening packages or breaking down boxes to recycle. Would recommend and buy again." —Amy Yasneski

Get a set of six from Amazon for $6.49. 

Check out a TikTok of the double-sided cutting board in action. 

Promising review: "This cutting board is perfect! One side is for meat, the other for fruits and vegetables. There is no need for two separate boards. It's very stylish, made of sturdy materials, and easy to clean. It's so pretty I just leave it on the counter, but it does have a handle for hanging." —Jowana Lamb 

Get it from Amazon for $16.99+ (available in two sizes). 

According to Johns Hopkins, you may want to avoid diffusing oils around larger groups and young children because of the side effects of different oils. You may also want to avoid using an oil diffuser around pets with breathing problems, according to the ASPCA.

Promising review: "This is the most beautiful and calming aromatherapy oil diffuser I have seen. This is incredibly easy to use and features various timer buttons that can be shut off at your discretion. I love to watch its realistic 'flame' effect. The scent emits wonderfully. It also looks beautiful in my home. This was a great value for the price and great quality." —Amanda
