These briefs with a secret pocket & 39 other things on Amazon that were designed by geniuses

Every once in a while, among the countless items that make you ask yourself, "Do I really need this?" you come across something that was clearly designed by a genius. While said genius may not be a household name or the CEO of a Fortune 500 company, you appreciate them nonetheless — because they've effectively created a clever product that's basically life-changing. So what, exactly, separates the brilliant products from the ones that inevitably turn into unnecessary clutter?

Modern-day consumers tend to appreciate things that are sleek-looking and well-made, but in my opinion, that's only half the battle. In order for an item to truly make a difference in your day-to-day life, I'm of the belief that it has to be practical. A purchase might be aesthetically pleasing and it might utilize quality materials, but if it's purely decorative, it's likely not going to make much of an impact.

Luckily, Amazon is filled with hidden gems that practical people will love, and the high reviews are more than enough to prove it. Whether these gems aim to streamline your routine, improve your sleep schedule, or boost your overall sense of well-being, they were clearly designed by a genius who believes in solving everyday problems in innovative ways.

1. These comfortable briefs with a hidden pocket

Whether they wear them while traveling, running, or attending festivals, reviewers love Speakeasy Briefs and write things like, "They are a must have." That's because, aside from the comfortable cotton-modal blend, they also have a hidden pocket for your cash, passport, house key, phone, or secret alcohol stash. "They fit a lot and it doesn't look suspicious!" Get them in two colors and two sizes.

3. A three-in-one insulated can cooler to keep your beer cold

Even those who drink quickly encounter the dreaded lukewarm beer at the bottom of the can — and it's bound to happen to those who prefer to sip one drink all night. The BrüMate Hopsulator is a three-in-one insulator that works on 12-ounce cans, 16-ounce cans, and in place of a pint glass. The double-walled stainless steel and the copper layer keep drinks up to 20 times colder.

4. A sleek, stackable charging station

The PowerCube is not your average outlet strip.

Get it in your choice of four colors.

5. This nootropic gaming supplement that aims to improve focus and clarity

Gamers have given this nootropic supplement a 4.8-star rating because its carefully chosen ingredients help to keep you locked in with mental clarity, energy, and a quick reaction time. That said, it's not just for gamers — those who work in front of a computer all day also appreciate that it helps to alleviate eye-strain and boost focus: "I really wanted to try this to see if it would help me focus better at work [...] I have noticed an increase in mental clarity and energy."

6. A bedside shelf when you don't have room for a table

This genius invention is great for bunk beds, small rooms, and those who don't have space for a bedside table.

Reviewers love them because they're easy to clean and great for packed lunches.

8. A facial foundation that adjusts to any skin tone

Whether your skin tone changes seasonally or you can never seem to find a match in the drugstore, LDREAMAM color-changing foundation aims to save you time, money, and effort. Its creamy consistency moisturizes while evening out your complexion, and while it goes on white, it quickly changes to blend in with any skin tone. Best of all, reviewers said the full coverage "lasts through a busy, sweaty 12-hour ER shift!"

9. This brilliant tool so you can open your door hands-free

Never again stand at the sliding door with your hands full and hope someone outside notices. The Smart Slider is a hands-free solution that attaches to your door with included Velcro adhesive.

10. A toilet brush that stays hidden behind the tank

A toilet brush is a necessary tool, but that doesn't mean you should have to stare at it. From the makers of the Squatty Potty comes this genius cleaning brush that stays hidden behind your toilet.

12. Some patches that help heal blemishes overnight

Since they're packed with absorbent hydrocolloid, these pimple patches suck all the gross stuff out of a blemish overnight. Simply cover the spot with one of the 72 hypoallergenic dots and head to bed. In the morning, you'll likely find that the patch is cloudy with the former contents of the pimple and that the area is less red and inflamed than it was before. No wonder buyers have given these a 4.6-star rating.

13. A magnetic key holder so you're never locked out again

Made with a strong, high-performance magnet, these little storage containers keep your keys safe and hidden in convenient spots. They work with most car and house keys, so you can stash them underneath your bumper, inside your fuel door, underneath the metal mailbox, or inside the downspout.

15. These stretchy shoelaces that never need to be tied

16. A light bulb that encourages sleep-inducing melatonin

Short-wave blue light is present in most bulbs (as well as the light from device screens) and it has been shown to impede melatonin production, which is the hormone that helps you to fall asleep at night. The Sleep-Shift bulb, on the other hand, produces a soft orange glow without visible blue light, so you can slip off into a peaceful sleep. Plug it into any existing lamp or fixture and turn it on while you read or get ready for bed. "I start feeling progressively sleepy beginning about 30 minutes later," one reviewer wrote.

17. This starter kit so you can save money on homemade kombucha

Kombucha is a great source of gut-healthy probiotics — but it's also pretty pricey when bought by the bottle. Fortunately, you can make your own with the Get Kombucha starter kit. It comes with everything you need to brew your own at home, including the certified-organic whole leaf tea leaves, cane sugar, a scoby, pH strips, and cotton covers. Reviewers call it "easy, delicious, and downright fun."

Despite the fact that it fits in the palm of your hand, the LectroFan Micro packs a serious punch.

Three customizable heat levels blow out from the center of the brush, while the ion-generating bristles keep hair taut and smooth. The result, according to reviewers, is smooth, styled hair in record time.
