39 Things On Amazon That Are Pure Genius & Under $30

This bath pillow is so comfortable, you might just doze off while you soak. An extra layer of cushioning bolsters the head and neck, while the wings on each side support the shoulders and upper back. The wave stitching gives softer support to sensitive areas like the spine and shoulder blades, and the 3-D quilted mesh material won't stick to your skin like vinyl. Six strong suction cups keep the pillow firmly in place — and it dries quickly when you're done using it.

Give your feet an actual massage while you shuffle around the house in these reflexology slippers. The admittedly very strange looking slippers are outfitted with 41 strategically placed acupoints that massage the feet while offering reflexology therapy. In case you're not familiar, reflexology is a traditional Chinese medicine practice that uses applied pressure on specific parts of the foot to stimulate circulation and promote healing in other parts of the body, like the neck, ear, or stomach. Wear these for about 15 minutes a day to reap the full benefits.

Your feet do a lot of hard work; give them some much-earned TLC with this shower foot scrubber.

The scrubber is made with quick-drying silicone — you don't have to worry about bacteria build-up — and it's available in four colors: blue, pink, gray, and clear.

Keeping everything in your suitcase once you reach your destination is a recipe for frustration. (Somehow that one black T-shirt has always gone missing.) Unpack and display everything on these hanging luggage organizers. The three-tier organizers hook right onto a closet rod where they provide space for pants, shoes, pajamas, that one black T-shirt, and more. When they're not hanging, the organizers collapse flat so you can easily pack them in your suitcase.

Keep your phone fully charged — even when there's no outlet in sight — with this portable power bank.

With an impressive 4.4-star rating, reviewers say this stain remover is "the absolute BEST at removing any stains from garments," and has "never met a stain it couldn't handle." All you have to do is apply a drop of the remover — no scrubbing involved — and you'll be able to work out even tough, set-in stains.

These air purifying bags are a great way to keep your home smelling fresh without having to use diffuser sticks or air freshener. The bags are filled with bamboo charcoal, which naturally absorbs excess moisture in the air and neutralizes odors. And they can be used for up to two years — just set them in the sun once a month to reactivate. Each order comes with 12 small bags; stick them in gym shoes, closets, cars, or use a couple to freshen up larger spaces like living rooms.

With over a thousand reviews and a 4.5-rating, you know this inverted umbrella has got to be doing something right. Instead of folding down, the umbrella folds up — so you stay dry when getting into your car or boarding a bus or train. That inversion also keeps floors and belongings from getting wet since the dry interior of the umbrella becomes the exterior once it's folded up, and the C-shaped handle fits over your wrist to free up your hand to find your keys. Choose from dozens of colors and designs.

You know that drain on the side of your bath tub just under the faucet? It's there to prevent overflowing by draining water once it reaches a certain level. But that drain can also keep you from getting an extra-deep bath. (Sigh.) This bathtub overflow drain cover, though, moves that drain a few inches up by blocking the existing drain while still allowing excess water to flow through, thanks to the 1-inch hole at the top of the cover.

Cat and dog owners: if you're having trouble locating the source of a not-so-pleasant odor, use this black light flashlight to find it.

An added bonus is that it finds all kinds of other hidden stains that you can then clean up."

The thermometer connects to an app on your phone where it creates individual profiles for each member of the family, stores readings, interprets temperatures based on age, tracks symptoms and medications, and provides guidance on what to do next. Use it whenever you're sick, or use it to track temperature changes for family-planning purposes.

Soothe a sore throat and boost your immune system with this throat spray made with bee propolis.

Spray this in the back of your throat during cold season or anytime it starts to feel a little scratchy.

This sleep mask quite literally helps you get your beauty sleep. The unique mask is infused with copper, which helps promote collagen production. In other words, wearing the mask over time can actually plump the skin around your eyes, so you look well-rested even if you didn't get a ton of sleep. Of course — you probably will get a ton of sleep, since the mask also performs that all-important task of blocking out light.

This very-satisfying-to-use blackhead remover actually uses the power of suction to vacuum out dirt, oil, and impurities from your pores, leaving you with clear, smooth skin.

These USB-C charging cables have over 2,000 glowing reviews, with buyers writing that they're "super fast charging," and "the best USB C cables on the market."

Reviewers say you'll start noticing an improvement within a couple days, with noticeably whiter teeth after two weeks.

This hair straightening brush straightens hair twice as fast as a flat iron, which cuts down on styling time in the morning and minimizes heat damage.

It shuts off automatically in 30 minutes and the accompanying silicone pouch lets you pack it in your bag without having to wait for it to cool. One reviewer wrote: "I would give this product ten stars if I could!"

The top of this travel makeup case flips open, so you can get a complete view of all your makeup — instead of having to dig through a jumbled up bag. Made from Oxford cloth with a spill-proof interior, the case features a zippered mesh pocket and padded divider inserts that can be configured any which way to maximize space. Choose from fun patterns, like flamingos, flowers, or the lemons pictured here.

This hair serum is made with fractionated coconut oil, which penetrates deeply into the shaft of hair strands to deliver deep hydration and nourishing fatty acids. The formula is boosted by other moisturizers, like almond oil and aloe, along with growth-promoting algae extract and hair-strengthening keratin. Apply this after towel drying: it'll protect hair from heat damage and give it a glossy, silky smooth finish without weighing it down.

Use this hair waver on 1-inch sections of hair to create tousled, natural-looking waves — or use it on larger sections to create a sculpted look worthy of any retro silver screen goddess.

Dual voltage makes this super travel-friendly, and an automatic shut-off function ensures the waver turns off... even if you forget to unplug it.

Create sleek chignons, romantic updos, and dressed-up ponytails with the help of these hair tail tools.

Each set comes with four pairs of tools that work on all hair types — use the smaller tools for intricate work and the larger tools for looser, sweeping styles.

Cleaning your hair brush may not be first on your list of tasks, but the truth is that there's probably a significant build-up of oil and styling residue on the bed and bristles — which you probably don't want to be brushing back onto your hair. Use this hair brush cleaning tool to clean it — the comb-like end works the strands out of bristles, and the broom-like end sweeps away dried oil and residue from the bristles and bed.

This hair dryer brush is a dream for any of us who aren't particularly talented in the styling department. It dries and and styles at the same time, and — depending on how you use it — can give you a smooth and sleek look, major volume, or a slight curl or flip at the ends. The brush features a combination of nylon pin and tufted bristles, three temperature settings, two speed settings, and an oval design that gives even fine hair a boost of body.

Make a better caprese salad with this ingenious tomato slicer. The slicer grips the tomato and the dividers guide your knife as you slice it into precise, uniform segments. It's dishwasher-safe and works with other produce too — slice onions for burgers, cut up lemon for water, or use it to make scalloped potatoes.

With this bug zapper, you can keep mosquitos at bay without the use of chemicals or strong scents like citronella. The black light of the zapper attracts bugs and then zaps them, which means you can spend a long summer evening in the backyard without having to deal with a lot of itchy bites afterward. The zapper also keeps houseflies, midges, and fleas at bay, so you can live your best bug-free life.

This four-in-one fruit slicer features different blade configurations that allow you to make small wedges, large wedges, and halves — which means you can use it for apples, mangos, pears, guava, and citrus.

The slicer comes with eight fruit forks, so you can dig in right after slicing.

Organize and charge all your smart devices with this charging station. Made from eco-sustainable bamboo, the station has slots for six phones or tablets, a magnetic stand for a smart watch, and a tray for thumb drives.

Lettuce that's crisp versus lettuce that's soggy can make the difference between a good salad and a great salad, which is why a salad spinner is a must. This salad spinner doesn't just dry lettuce leaves, though, it also rinses them first. After putting your lettuce in, pour a little water into the outlet, then pump to spin. After that, pour the water through the spout into the sink and spin a few more times to thoroughly dry the leaves.

Removing a cheesecake, tray of lasagna, or frittata from a pressure cooker is tricky, but this pressure cooker sling makes it a cinch. Made from heat-resistant and dishwasher-safe silicone, the sling is designed to fit into 6- and 8- quart pressure cookers and multi-cookers, like the Instant Pot. Just place your tray or bakeware onto the sling, lower into the pot, then interlock the handles so they tuck neatly under the lid. When done cooking, simply lift up the handles to remove —without risk of spills or drops.

These highly-rated bottle scrubbers are a great addition to your dishes routine. Use the big fluffy scrubber for glasses, stemware, and to-go cups, the medium scrubber for champagne flutes and reusable water bottles, and the two skinny scrubbers for reusable straws. The extra-long handles make it easy to reach into jugs and decanters, and scrubbing bristles are safe to use on all kinds of surfaces — including crystal, stemware, and stainless steel.

This is not your average cutting board. It actually pops out to create a basin where you can rinse your fruits and veggies before you get to slicing. The drain at the bottom of the basin allows water to flow freely through, but you can also twist the plug to keep water in if you want to use the basin to wash dishes. The handles on each side make transporting it to the counter easy, and because it collapses flat, it takes up minimal storage space.
