It ain’t no lie, these products are genuinely helpful.

Promising reviews: "Great for 'under the skin' bumps. They work well and quickly overnight. For more serious spots, I will put them on for a few hours, rest, then reapply. I am a picker, so this really helps keep me on a track to recovery." —Kirsten Stocksett

Get it from Amazon for $13.48+ (available in six styles and in a 2-pack).

Promising review: "FINALLY, COMFY PANTIES! As a 30-year-old woman, I’ve been on the search for comfy underwear, and I finally found it. They’re soft and have the perfect amount of stretch." —Amazon Customer

"So freaking comfy. I need my undies to cradle under my butt cheeks the way a loving mother tenderly cradles her newborn’s face. I was worried these would creep up the cheeks into wedgie territory, but no. Blissful cheek hugging all day long. Can’t feel them even if I try. No weird pinching or odd areas. Perfect chef’s kiss. I typically wear Aerie boy brief–style undies — these are a close match in fit and comfort, and equivocal in size." —Ali Morey

Get a set of five from Amazon for $14.98+ (available in women's sizes XS–3XL and 11 color combos).

Promising reviews: "I need this in bulk!! I have tried so many cleaning solutions to get out hard cooking stains on my stove top, and nothing worked! This stuff took it right out without a problem!!" —Micaela Gunderson

"I was trying to get adhesive off of drywall, and nothing was working. THIS WORKS on everything! It easily took off the adhesive. Then I had Corningware with a stubborn stain; I had tried everything. Then I tried The Pink Stuff, and it easily removed the stubborn stain. I will now always keep this on hand!" —David C. Rein

Promising review: "I’ve used Color Catchers for many years, so I can wash darks and lights together. They save time and money. (I’ve given boxes to each of my children as they head off to college.) You can tell they work because you see the color they soak up. Recently, a new purple shirt took me by surprise and ran profusely. I had two color catchers in that load, and they both turned deep violet." —Go Steelers 

Promising review: "I was surprised by the difference these new shower curtain hooks made. They slide SOOOO much better across the shower curtain rod than the ones I had previously. There are also two hooks (one on each side), making it a breeze to change out or wash the shower curtain liner without removing the shower curtain. This saves so much time and aggravation!!! I will be purchasing this type from now until forever!" —MaryMaryinLA

Get it from Amazon for $6.99+ (available in 21 colors).

This medium-coverage concealer can be applied with your fingers or a brush.

Promising review: "I believe I was born with dark circles under my eyes, and I have spent the last 50+ years looking for something that will cover my dark circles. I’ve spent a lot more money on products that do a lot less. And I was very hesitant to buy something so inexpensive, as I thought it would not work. I was surprised to find my circles a lot lighter, and my eyes are looking much more alert and younger. I’m very pleased with this product!" —Lafinrsm

Get it from Amazon for $6 (available in four tones).

Promising review: "This is a very clever solution to a real problem experienced by anyone maintaining his beard. How to avoid beard whiskers making a mess of the bathroom when trimming. It is very easy to use and saves time by eliminating having to clean up after trimming." —Dim

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

Promising review: "Fabulous water pressure and it really does a good job of getting stuff out of your teeth. I was skeptical, but I used it and then manually flossed afterward, and there was no plaque or food bits to be found!" —Bea Goodwin

Get it from Amazon for $19.99+ (available in three colors).

Promising review: "This is now my go-to pet hair remover. I have a long-haired golden retriever, and my girl SHEDS a new dog's worth of hair almost daily. I've tried heavy-duty tape rollers, rake-style pet hair removers, but the ChomChom beats them all." —alw91

Get it from Amazon for $24.99 (available in two colors).

Promising review: "This product is exactly as shown. Rubber backing keeps it from slipping off. Just the right size to hold everything you need. I recommend it." —Madelyn White

Get it from Amazon for $11.99+ (available in two sizes and nine colors).

Promising review: "I love WD-40 products and use them for everything. I spray on shovels to keep dirt or snow from sticking, spray around windows and thresholds to deter bugs, clean Sharpies off wood and walls, and, of course, stop squeaky doors. These small direct-point application pens are great. Keep one in the glove box, my kitchen 'junk' drawer, and in the house toolbox." —BBP623

Get a three-pack from Amazon for $12.49.

Promising review: "Holy grail. This is my favorite moisturizer! Its consistency is perfect. I have combo skin, and I struggle to find something that leaves my skin soft and not sticky or lacking the moisture I need, and this meets both of those. It’s also extremely lightweight, zero greasiness at all, smooth, and has no weird smells. I will forever buy this. It’s helped repair my barrier and keep my skin looking vibrant." —Liss

The water-resistant light comes with a replaceable lithium battery.

Promising review: "So glad I found these. I have one on my apartment key and another on my mailbox key. They really work well, especially in low lighting. Since my vision is no longer perfect, these lights save me time so I don’t have to fumble trying to get my key into the locks. I definitely recommend them. I have a spare for replacement, but they last a long time." —Marni

Promising review: "This body spray has helped clear up stubborn back and shoulder breakouts better than anything I’ve tried. The 360-degree spray makes it super easy to apply, even to hard-to-reach spots. It dries quickly, doesn’t stain clothes, and has a clean finish. After a couple of weeks of consistent use, I saw smoother skin and fewer breakouts. It’s also lightweight and doesn’t feel sticky. Definitely recommend for anyone dealing with body acne." —Rosiemelisa

Get it from Amazon for $14.87 (also available as a two-pack). 

Promising review: "I never understood how people could go more than two days without washing their hair, and now I know. This has been a lifesaver! I was looking for an alternative to my spray dry shampoo, and this is even better. It literally dries up the oil and makes hair look freshly washed." —Mandy

Get it from Amazon for $13.59+ (available in three shades).

Promising review: "This Christmas gift was the perfect cure for my hard-to-sleep nights. Within just a few minutes, I was out cold. Talk about feeling refreshed this morning!! I may even skip my coffee, haha! We are taking it for a trip we have coming up because it’s so easy to use, small and compact for packing, and let’s face it, hotels are the hardest places to sleep, so we think this will be a game changer for us." —A C

Get it from Amazon for $18.99+ (available in three colors).

Promising review: "I'm in love with these; they helped me get organized with all my bedding! A set of sheets fits perfectly. Easy to assemble, durability is great, easy to clean, and a huge value for the price." —Christy Hawkins

Get a six-pack from Amazon for $29.97+ (available in eight colors; also available in a nine-pack).

Promising review: "Since starting, my bladder control has significantly improved. I am now able to sneeze or cough without peeing myself. Yes, that's right. I am able to hold my pee longer, which means I can actually make it to the bathroom without dribbling on myself. The best part is that just a few short weeks into the program, you will have results that you can feel. I think anyone who has ever had kids should try this out. The overall quality of my life has improved. Ditch your panty liners, stop the embarrassing dribbles, and no more mad dashes to the restroom because of a weak bladder. Even my sex life has improved; I have control of those pelvic muscles now. Just remember to wash the weights before and after each use with an antibacterial spray, and allow time to air dry before putting them away. I say air dry because if you wipe them dry with a cloth you run the risk of giving yourself a bladder infection or urinary tract infection, and those are no laughing matter. Easy to use, easy to clean, stores away quickly." —Julie Tauber

Get a set of six weights from Amazon for $49.99.

Promising review: "Wow. This works fast. As soon as I put it on, I could feel it working. I was surprised by how well it covers the sore. I thought, 'Is this thing magic?!' It stays put, too. I put it on last night and already feel so much better today, and it looks a lot better. This is important to have in stock just in case this comes out of the blue, which is what happened to me. I’m so thankful for the people who created this. This is the best product I’ve ever used. And I’ve used others with no effect. This is powerful stuff." —GG

Get a pack of 15 from Amazon for $12.97.

Promising review: "This is the best pill container I have found. It holds a month’s worth of pills in each compartment and is compact and easy to store and travel with. It is very sturdy, and I don’t have to worry about the cap opening accidentally. The enclosed labels are a bonus, and the see-through exterior makes it easy to see how many pills are left. I keep it on my nightstand, and it doesn’t take a lot of space." —TA

Get it from Amazon for $7.58+ (available in six colors).

Promising review: "This face wash is wonderful! I have never repurchased a face wash this much in my life. I use it every day. I have very sensitive skin that is very prone to breaking out/dry skin, and this has kept my skin under control for about two years now. I do use moisturizer immediately afterward, so for me, it is not drying at all. And I love that there is no scent and no residue on my hands when I’m done. It feels very clean." —Jade W.

Promising review: "I’m not usually blown away by products, in fact, I’m used to being a little disappointed. But not with this product! This stuff is perfect for traveling. It got rid of wrinkles and static quickly, and the scent is an added bonus. Would definitely recommend and will be buying more." —DdWojo 

Promising review: "Bloom is my favorite. Does not make you jittery. Tastes good, and the texture is smooth like a flavored seltzer." —Amazon Customer

Get it from Amazon for $23.50+ (available in nine flavors and in a variety pack).

Promising review: "I have super oily skin and am always looking for something to help control it during the day. The linen squares are good, but you have to keep them around (and keep replacing them), and they end up in the landfill. This little contraption really works, and I just rinse it at the end of the day and start over again the next. I kept one on my desk and bought a second for my purse. This is magic for my shiny skin, especially on camera in my hours of Zoom every day." —Jennifer Helseth

Promising review: "This product deserves more than 5 stars. It is such a help. I am 76, and we have an 18-inch Sterns and Foster mattress, so you know it's big and heavy. It is really difficult to change sheets, and I do this each week. I am so picky about how the bed is made that my husband doesn't like to help. (He is 80.) I changed sheets last night, and these mattress lifters were a gift from above. I can't believe how neat and tidy my bed was after using these. What a big help! I am so grateful to have found these extra hands. I have two of these and recommend them as a set because I tried with just one, and two make it so much easier." —Scrapbook girl

Get it from Amazon for $16.95+ (also available in a two-pack).

Promising review: "I absolutely love these things! I have five kiddos. These gel stamps keep my toilet cleaner and fresher-smelling for longer, which is a definite plus with four boys. These have an easy, no-mess application. I finally just put them on my Subscribe & Save so I always have them ready." —Alyssa M

Promising review: "For anyone with long hair, drainage clogging in the shower is a pain. So, THANKS to whoever thought of such a simple but clever solution. They stick perfectly, and the glue lasts like three weeks. It literally does not let a hair pass, and it's just so easy to place and remove. I wish I had known about this product before! A must-buy." —MER

Get a 25-pack from Amazon for $11.39 (also available in a 50-pack and 100-pack, and a square size).

Promising reviews: "Does the trick of getting hair out of the roller. Happy I bought it." —Pat S

"Between myself (medium long hair) and my overly fluffy cat, a lot of hair and fluff was continually getting caught up on the roller brush of my vacuum. I dreaded vacuuming because it took so long to pull and snip the hairs wrapped up on the roller brush out with scissors. Not anymore! This silly, little, inexpensive thing works great! Super quick to remove all the hair/fur — in virtually a minute, then back to vacuuming with my lovely Miele vacuum." —MKS

Promising review: "I love this keyboard cover. It has a nice feeling, is very flexible, and fits like a glove on my MacBook Air. It doesn't come off even when I'm moving my laptop around a lot (which I do since I do a lot of work on the sofa or the bed, where I end up in weird positions to be comfortable). I can feel each key individually when I hit them, which is really nice. I also type a lot due to work and school, as well as simply writing in my free time, and this cover has held up the entire time. I haven't seen any signs of wear or fading in the six months I've had it. This is a very durable keyboard — I eat with my laptop all the time, and I've actually spilled coffee on my keyboard once, and nothing happened — it actually kind of kept the liquid there until I could clean it off. I would definitely buy this again if I needed another color." —Sadia Rahman

Get it from Amazon for $5.89+ (available in nine colors).

Promising review: "This is great for teaching different types of breathing to help calm down. The distraction of following the directions can take your mind off your anxiety pretty quickly. There are several types of breathing techniques to choose from. Kids love it because it lights up and changes color." —L. Demro

You'll get three attachments, a bendable wand, two extra filters, and a wall mount.

I've had this vacuum for about three months now, and it has yet to disappoint! It's lightweight and easy to carry, which makes cleaning the entire apartment super easy. It moves from carpet to wood with ease, and its suction capability is similar to that of the Dyson V8 (which I maaaaybe used to have and accidentally broke 😬). Plus, its anti-tangle brush makes easy work of gobbling up my roomie's hair (I'm bald, so it ain't me) without, well, getting tangles in it. And it comes with enough attachments to clean just about anything/anywhere. All at *that* price point? Yeahhhhh, I'm sold. Well, I already was, but you know what I mean.

Patellar tendon straps like this one can reduce strain on the tendon connecting your kneecap and tibia during physical activity. While this can help reduce pain, talk to your doctor about recurring pain so you can address any underlying issues. Learn more about patellar tendon straps at Cleveland Clinic, and chat with your doctor to see if this is right for your knee pain.

Promising reviews: "I broke both knees, so using these straps is a must. These are by far my favorite as they make my knees feel secure. Gave to my dad as he is also bone-on-bone, and he loves them." —Renee

"These are great. I'm not even aware I'm wearing them. They just work. I use them on my rowing machine (allows me to use much more force in my legs), bowling, and walking. I walked 582,000 steps in one month with NO PAIN! Wow." —John Schaeffer
