If I had Shark money, I’d invest in all of these brilliant designs.

Promising review: "I recently switched to cycling for my work commute, which means bike maintenance. Regardless of how easy its been, it always results in at least some grease and dirt on my hands and I almost never could get completely clean. I just used these wipes about an hour ago after replacing a flat tire, and that one instance has compelled me to post this review. I used a single wipe and was able to completely clean up my hands and arms in less than five minutes. You couldn't even tell that I had been fiddling with my bike; no grease or grime remained. I highly recommend these! I will be carrying two of these individually packaged wipes in my bag with me whenever I'm on the bike considering how useful these would be if I had to do some roadside maintenance and had no way to clean up. Get these if you do any sort of work with your hands during which they may get some grease or grime on them." —V Cash

Promising review: "I love this product. This has been a great, inexpensive gift for all of my teacher colleagues and friends who are on the go. I am very rough with my keys and often drop them or throw them in my bag and desk drawer, and it hasn't shown any signs of breaking or coming apart. My original intention for my latch was to keep it on my keys so I'd always have a place to put my earrings and rings when they start to bother me. Since I've become pregnant, I currently use it to store extra prenatal vitamins for the mornings I rush and forget to take them. I appreciate the compact size and the surprisingly large amount of small items it can hold." —MCren

Get it from Amazon for $17.95 (available in 10 colors).

Promising review: "If you have a reverse osmosis system this is essential for coffee. I love RO water for just drinking, however for coffee, mixing this in gives a very robust, aromatic coffee. The first cups I made with RO water tasted very bland/flat, nearly like nothing at all. This with dark roast tastes better than most cups I get at places that make you pay $4 for a cup." —J. Press

Get a box of 12 capsules (which makes 12 gallons of water) on Amazon for $18 (available in light roast and espresso).

Promising reviews: "Great box cutter. Safe with very little chance of cutting yourself by accident. Feels good as it easily cuts through any cardboard box. Sam’s Club ships with giant boxes, and I like using the BoxBlayde on them because it’s much easier than using a utility knife. Also, my utility knife blades will fit in my BoxBlayde. You can tell when you put this in your hand that it’s well-built and not cheap. This is a high-quality box cutter. If you have a lot of boxes to break down, this is going to help you get it done faster." —Amazon Customer

"This item is just great. It is powerful and easy to use. I have been breaking down the strongest of cardboard, no problem." —Rhonda R. Harris

Pizza Pack is a small business that specializes in sustainable food storage solutions. 

Promising review: "It's always a pain to put away leftover pizza. It never seems to work. UNTIL THIS PRODUCT!!! I am very happy with my purchase. It's easy to keep the pieces separate from others and you don't have a large bulky box letting your crust dry out. You can use it for one piece or several — it is very easy to expand. The best part is that it is very easy to clean. Storing the Pizza Pack when not in use doesn't take up a lot of space either. Try it." —B. Cirincione

Get it from Amazon for $24.99 (available in eight colors and multipacks). 

These are FDA- and USDA-approved, and BPA-free. Plus, they're made of sturdy, resilient, and flexible material, and they're dishwasher-safe! Wanna learn more? Check out one BuzzFeeder's full review of the Spatty Daddy!

Promising review: "So worth it! I'm so happy with it. You will definitely save money using this. I think about how much I could have saved if this was invented 30 years ago. I mostly use it for small makeup jars. I tested out the Spatty Daddy on an 18-ounce lotion and it worked fine. You get so much more makeup than you would without it. I give it 5 stars." —Liz

Get a pack of two from Amazon for $9.99.

Promising review: "No more wasting product. I love these so much that I had to get the six-pack so I can use them around the house for everything. I love that once the bottle is done, you just clean the lid and put it on something else. I love that the bottles don’t fall while the product is slowly dripping inside the bottle, and if you use the stoppers, it doesn’t leak. The only thing is, I wish it came with a lot more stoppers. This is a must-have in your house." —Must buys

Get a six-pack from Amazon for $19.99 (available in two colors and smaller pack sizes).

It's best for baseball caps with flat or mildly curved brims and stiff faces. 

Promising review: "If you are as tired of your husband's hats on every hook and crook around your house as I was, this is what you need to have. It works just as described. We have tried several different style hat keepers, but they took up a lot of room and weren't as easy to use. This condenses them down into a small space, and even if the cap he wants is on the bottom, he has easy access to it. Best of all, HE likes it! I will be ordering another one." —Missy's Mom

Get it from Amazon for $19.99 (available in white or black). 

Tik Pik is a small business founded by two guitar-playing friends who were sick of losing their guitar picks. 

Promising review: "Stays in your fingers, sticks to things. It does everything as advertised. Almost has a suction cup feeling in your fingers. Very durable. Seriously, just buy it. You won't regret it. The case is really nice, too. Love it." — Nicole 

Get a six-pack from Amazon for $29.95 (available in four weights and as a three-pack). 

Promising review: "Obsessed!!!!! I was hating seeing (and hearing) my little baby girl have boogies and then having to spray saline up her nose to make them moist and then suction them out. It seemed that there had to be an easier, less invasive way. Q-tips wouldn't scoop it, and I was too nervous to use anything else as I did not want to push up her nose too far. This is so easy, clean, and safe!!! Love love love!" —WhitneyB87

Get it from Amazon for $9.98+ (available with an without a case).

Promising review: "This thing is freaking awesome!!! So I am NOT a barber, but I have over the years almost perfected a fade on my husband. The only thing I couldn’t do perfectly was point his sideburns; he has a very specific way that he likes it, and when I tried it, it just fell short. I saw this product on Shark Tank again (as an update) and decided to give it a whirl for only $8 what do I have to lose right? Well I used it for the first time and he got the best haircut to date. The sideburns look great, but also I used all the angles all over his head and it made it so seamless and easy to cut all along every edge. Pics are after first use, so I feel I will get better with using it with time (I also accidentally cut his top with a 3, not a 2 so his cut will look even better next time) but I highly suggest this to anyone who cuts men’s hair be it in the home or at the barber's. I should also mention that HE is super pleased with how it looks. I can’t speak for using it on a beard yet but we are both so pleased with this product, seriously, buy it!" —Laurie Higgins

Get it from Amazon for $9.95 (available in two styles).

CowPots is a small business started by the Freund family, dairy farmers based in Connecticut. 

Promising review: "So far, I love them. I saw the founder on Shark Tank and was REALLY impressed by what they were doing and some of their future products as well. As an avid and Master Gardener, I thought, 'This is brilliant!!!' I have some and am starting seeds right now. Such a simple idea with a win-win model. LOVE these and the company's vision. I have placed another order for more, in fact. I'm not buying peat pots (peat bogs take hundreds of years to form and are not a practical resource) or plastic ones anymore." —Kim 

Get a 12-pack from Amazon for $12.69+ (available in two sizes). 

This cleaner is free of VOCs, alkyphenol, surfactants, and petroleum, and was not tested on animals.

Promising review: "I was looking for a safe natural product that didn't have any ingredients requiring a hazardous waste disposal label. A lot of so-called 'natural' cleaners have ingredients that need an EPA use-and-disposal label. This doesn't. It is strong enough to really go through grease and grime like a clear organic tornado. I haven't found anything that can't be cleaned with it yet. Plus it's odor-free. I feel comfortable spraying it in places where pets, children or myself in bare feet might absorb it by stepping in the residue. It's hard to get excited over cleaning spray but this deserves a level of excitement in my home." —Mark O.

Get a pack of two on Amazon for $12.99+ (available in three sizes and scents).

Splash Place is an Arizona-based, woman-owned small biz!

Promising review: "My daughter tried the other version of swim goggles that you normally find in a store but had difficulty using them. We purchased these instead, and I cannot give them a better recommendation. They are absolutely easier to put on, and they do not pull hair like the others. I will buy more as long as these are available, and I will gladly recommend them to anyone." —Lisa Krause

Get it from Amazon for $24.95 (available in 13 styles with more on the Splash Place Amazon Store Page). 

Read more about acupressure and stress at Cleveland Clinic.

Promising review: "I am always looking for new solutions to help my chronic pain, and I had a feeling when I saw the Q-Flex on Shark Tank that I needed one ASAP. I used to do acupressure with a massage therapist but had to stop for financial reasons, and this is a great way to get the same relief for a fraction of the price. This has been so helpful for relieving the tightness in my neck, back, and shoulders, and I’m so glad I bought it. Honestly, this has been the BEST. PURCHASE. EVER." —Amelia

Stretchlace is a US-based small business that specializes in elastic shoelaces. 

Promising review: "I saw these on Shark Tank, so I decided to try a pair. They are AMAZING! These are in shoes that I wear for workout classes that involve plenty of stepping and cardio... my shoes do not slip or feel loose at all, but stay as snug as if they had traditional shoelaces. No more loose shoestrings, no more tying, and untying. What a great invention! Hey, you little kids with Velcro fasteners, move over! Grown-up laces are here!" —Leah

Get them from Amazon for $10.99+ (available in nine sizes, 15 colors, and in round laces). 

Note: Each mint contains 40 mg of caffeine. According to the Mayo Clinic, up to 400 mg of caffeine is safe for most healthy adults. 

NeuroGum is a small business that specializes in caffeinated gum and mints. 

Promising review: "I've been using these NeuroMints for the past four years now, and absolutely love them. They have completely transformed my productivity — I'm not exaggerating. Coffee is great, but it gives me this high for like an hour or two followed by a horrible energy crash. These NeuroMints are on a whole different level. The level of focus and concentration I get from these is incredible. I guess their caffeine/l-theanine ratio is ideal because I am able to code for hours with these. They first got me through college, helping me focus on my studies. Now that I work in software, they keep my brain running." —JetDriveSolutions

Get a pack of 72 mints from Amazon for $24.99 (available in four flavors).

This bag is free of BPA, PVC, and latex.

Promising review: "I've tried a LOT of reusable bags. The fabric ones just get gross over time. The vinyl ones are hard to clean and aren't usually dishwasher-safe. There are other silicone ones that need a separate rod to close them that you can easily lose. This one is the most simple and easy to use. No separate pieces to lose. Can withstand any temperature/ microwave/ dishwasher/ whatever. And if they get gunky, they are very easy to clean, and I trust that they aren't hiding gross crumbs in any of the crevices. My only complaint is the cost — they are the most expensive and I wish they offered a bulk discount. If they were cheaper, I would use them for EVERYTHING (open cheese in the cheese drawer, all snacks on the go, etc)." —Megan A.

Drop Stop is a small business that specializes in car accessories. 

Promising review: "I just don’t understand why I didn’t buy this sooner. It’s one of those things that you’re not really sure why you need it but once you have it, you can’t live without. It saved my poor arm from having to dig my keys, cellphone, pens, french fries, hair ties, you-name-it from between the seat gap. Seriously, it’s awesome." —Sara G-M.

Get a set of two from Amazon for $24.99.

Promising review: "I LOVE them! They remove food off of dishes more easily than a sponge, and I just throw them in the top rack of the dishwasher and they come out spotless! They never smell and always rinse out nicely in between washings. These little gems even take off hard water build up from my shower doors! (I also use regular cleaners with them to do the trick.) I love these so much, I bought a bunch and used them as stocking stuffers last Christmas! Everyone loves them!" —DivaGranny

Promising review: "I'll do you all the courtesy of NOT adding a photo or video (You're welcome). This works. Whoever invented the toilet had their heart in the right place, but not their knees. This device mimics proper positioning, and you should get one. That is all. Thank you for coming to my TedTalk." —P.W.

Get it from Amazon for $24.99 (also available as a pack of five).

Promising review: "I didn't even think about my shower drain being such a problem with hair. We have a relatively new shower and the drain was starting to be slow, but not really a problem because the pipe has a long drop. I was watching Shark Tank and thought maybe I need to check this out. Wow, there was a lot of hair to clean! Three long-haired girls in the house! I started using this and it pulled all sorts of hair out. We change it about once a month. Easy to pull out and no breaks or rust. I keep buying!" —Kindle Customer

Get a pack of two from Amazon for $12.99 (available in four styles and larger multipacks).

Souper Cubes is a US-based small business that specializes in bake-and-freeze storage products. 

Promising review: "So happy that I found these. I’m the only one in my household who enjoys soup year-round. Have you ever tried to make homemade soup for one? I say it’s impossible! But no longer. I can brew up the stock pot with bone broth or my favorite home soup. Fill up my Souper Cubes, freeze, pop out, store my goodies in a freezer bag, and I’m ready for the next batch!" —Debbie R. Texas

Get it from Amazon for $21.99+ (available in seven colors and as a pack of two).

Wad-Free is a woman-owned small business!

Promising reviews: "It's a miracle product! Oh my gosh, I only had to run the dryer one time to dry the sheets instead of my usual four times. They looked cleaner,  too!" —Bonnie

"I was mildly skeptical, but it works exactly as promoted! I've used it five times and each time there's been no twisting of the sheets and no pillowcases balled up and still wet when the dryer goes off. Super helpful that it comes with two units, one for the top sheet and one for the fitted sheet, so I don't have to split them into separate loads. I no longer dread washing sheets and plan to buy some of these as gifts. LOVE it!" —Amazon Customer

Get a pack of two from Amazon for $19.99 (also available as a pack of four).

Heads up that it might not seem all that soft and fluffy straight out of the packaging, but reviewers note that if you follow the directions and allow it time to fluff up, it will expand and become super comfy!

Promising review: "I have three boys. They seem to destroy air mattresses and bean bags. This is made from a foam that actually does better being beaten up. The more they jump on it, the better it forms. It’s great as a chair for reading. And great as a mattress for sleepovers. We’ve even had adults sleep on it and they were completely comfortable." —BW

Get it from Amazon for $299.99+ (available in three sizes and seven colors).

It comes with two clips — the large white clip is great for lengths and layers, while the smaller blue one is for bangs.

Promising review: "I can't say enough good things about this product. I can't wait to tell people what I use on my hair. I hate going to salons. I think I'm one of the few people that have never left a salon feeling like I look better than before I arrived. It doesn't matter how much I've spent on the visit either. This product has been a lifesaver. I just look up YouTube videos and follow the instructions. I just have myself a layered A-line bob, and it's one of the best cuts I've ever had. It seems like this product would be too good to be true, but if you're patient, it's super easy to use. I honestly think it's harder to use the clippers on my son's hair." —Michelle H

Just add your noodles, fill with water to the water line marked inside the cooker, microwave for three minutes, and that's it! Perfect ramen noodles! Plus, this is BPA-free and can be put in the dishwasher!

Rapid Brands is a California-based small business that specializes in dishwasher-safe, microwaveable, BPA-free kitchen products. 

Promising review: "This thing is amazing. Crack the noodles, throw 'em in, put the spice packet in, fill the water to the line, microwave for four minutes, and they're perfect. Not too hard, not too soft. You can even add in frozen veggies at the start (just make sure they're under the noodles or on the side), and throw cheese on at the very last 30 seconds if you want. The handles don't get hot, so you can grab it right out of the microwave, and it's easy to clean to boot! This is just a DREAM for me when I'm feeling lazy. Oh, and they're dishwasher safe." —Jessica B

Promising review: "I seriously can't believe how well these little tablets work. I had the most disgusting Hydro Flask coffee mug — I tried everything. A bottle brush, different kinds of soap, vinegar, EVERYTHING, and there was still a seemingly impenetrable layer of black sludge inside. I let a tablet sit in each of my mugs for an hour or two, and the black sludge rinsed out COMPLETELY, without even scrubbing. They look brand new. What a magical product. No weird smell or taste afterward, either. I liked it so much I used it on another Hydro Flask I use primarily to hold my Bloody Mary mix in the fridge. I couldn't put anything else in it because it would always taste like spicy tomato juice. Bottle Bright to the rescue! No residual smell or taste anymore. AMAZING AMAZING AMAZING." —Amazon Customer

Get it from Amazon for $7.99+ (available in 12-, 36-, or 78-packs).

This is especially useful for students or anyone else who's always taking notes! The package includes the notebook (with 36 dotted pages), a Pilot Pen, and microfiber cleaning cloth. There's another version of Rocketbook that includes a planner!

Promising review: "I absolutely love these books. It’s so easy to take notes and upload them to the Rocketbook app and view them later. It also allows for me to only use one notebook for all my classes. Given that I can upload my notes — it makes it so much easier to study. Personally, I have a habit of losing the notes I take in class so having them uploaded to the app makes it easy and convenient to look at them when I need them. Overall, Rocketbook has really changed my academic life. I’m definitely going to continue to buy their products." —Justice A.

Frywall is a New York-based small business that specializes in protective kitchen accessories. 

Promising review: "I was frying chicken with lard and put too much in the frying pan. A few minutes after putting the chicken in, the lard began to bubble up, and if I hadn't had the Frywall in place, it would have spilled all over my stove. The Frywall creates a seal around my frying pan, stopping spillovers. Splatters don't escape; it's easy to work around it (turning my chicken over), and when I'm done, I just throw it in the dishwasher. If you do any frying at all, you want the Frywall. Helpful." —Carl G Brown

Get it from Amazon for $23.95 (available in four colors).

Nerdwax is a US-based small business that specializes in all-natural anti-slip eyewear products. 

Promising review: "I purchased this product after seeing it reviewed on the GizWiz podcast, which was featuring Shark Tank products. The product is super easy to use, immediately works as advertised, and allows me to avoid stopping work just to adjust my glasses." —Paul Alfredo Ayala, Sr.

Here's why BuzzFeed writer Kayla Boyd is a huge fan of it:

"I LOVE this thing. It allows you to literally wrap yourself in a blanket, but still be able to use your hands, without your poor arm suffering in the cold breeze. I wear this while working from home, watching Netflix, and while taking naps. It's so comfy that there have been times I don't want to take it off when I have to run to the store — the only reason I do is because I don't want it to get dirty. I can't imagine one person who wouldn't be happy to receive this wonderful bundle of coziness."

Get it from Amazon for $39.59 (available in a variety of colors/styles and with a zipper).

Promising review: "My girlfriend bought this for me as a present. At first I was skeptical to use it, but once I got my hands on it there was no going back. I use my Beard Bib anywhere from two to four times a week and cannot live without it. Not only does this serve a big purpose in my trimming routine, but now I no longer have to argue with my girlfriend about all the mess that I USED to create!" —Timur

Get it from Amazon for $4.98+ (available in six colors/styles).

Safety Nailer is a small biz founded by a veteran that specializes in tools that protect your hands.

Promising review: "I have this and the finish nail size, and they are both great! I have nerve pain in my hands, and the Safety Nailer removes any chance of me banging my fingers with a hammer. What a relief!! It’s great for those of us who are not as dexterous as we once were. One of the best construction gadgets I’ve ever purchased." —w4shep

Get them from Amazon: the regular size or mini size for $8.99, or a combo pack with both for $24.70.

Note that the suction can be pretty strong, so use caution and try a small amount of suction first before working your way up if necessary.

Promising review: "I am a magnet for bites of all kinds and carry topical and medicines with me at all times — so I figured this would be a good product to see if it really works. I woke up with a bug bite on my arm, so I used this little tool (three times per the instructions) — immediately after using it, it stopped itching! And less than 24 hours later, the bump/bite was gone! There is a very faint red mark from using the thing, but a small price to pay IMO. Bottom line: it’s awesome. I’m carrying it with me everywhere!" —Rebecca

Get it from Amazon for $9.99 (available in six colors).

Readerest is a US-based small business specializing in glasses accessories. 

Promising review: "I can't tell you how many reading glasses I've killed in the past few years, largely from jettisoning them from my breast pocket or hooking them awkwardly in my shirt collar. These clips are amazing. They're discreet enough that I don't look like a goon wearing one on my shirt all day, and when I hang my glasses from them, I can tie my shoes without spilling them lens-first on the ground. What else can a fellow ask for?" —Asha Ember

Get a pack of two from Amazon for $18.99 (available in two colors and a pack of two).

Vibes is a US-based small business established in 2015 specializing in unique hearing protection products. 

Promising review: "I saw the 'Vibes' on Shark Tank just the week prior to a musical festival-type event I was in charge of. I quickly ordered them — we all know how loud the music is at a festival. These were fabulous and worked just as shown, and as I expected. I usually leave these events with horrible ringing in my ears, but not this time! I was so happy to hear the great music but not experience the ringing." —AliceP
