Promising review: "I had a problem with my roommates going in my room and taking my things without asking. No matter what I did, they wouldn't bother to ask and they just treated it like it was their own storage room. Now, with this lock, they haven't been in my room since. And, the quality is excellent, so them jiggling the knob aggressively and pushing random buttons hasn't stopped it from doing its job. Thank you!!" —ET

Promising review: "The cult classic. IT REALLY WORKS. My roommates would complain EVERY time I went #2 (our house doesn't have an exhaust fan in the bathroom, which is truly awful), BUT NOW, it's like I never even went. I purchased the original scent and I love the citrus and lemongrass scent. The recommended 3–5 spritzes is spot on. I wouldn't do any less than three spritzes, and you definitely won't need to use more than five, the scent is very strong!!! 15/10 would recommend to anyone who poops." —Greg Hamilton

ChomChom Roller is a Massachusetts-based small biz creating an eco-friendly, reusable alternative to sticky lint rollers. 

Promising reviews: "Where has this been all my cat-loving life? Sticky rollers work fine for clothes, but this is the only product that has ever COMPLETELY removed all the cat hair from my bed. I have a long-haired, 20-pound tabby, and if you run your hands up his back a few times and fling the hair everywhere, it looks like it's snowing — he never stops shedding no matter what I do. After using the ChomChom, I can put on a black dress and roll around on my bed and not get a single hair on me. It's absolutely amazing. Everyone is getting one for Christmas, even if they don't have a pet. I don't care; it's THAT good." —DH

"Awesome!! My roommate's cat sheds like it’s her job, and there was hair all over our suede couch. This product is perfect for fixing that! I have tried SO many things and this is the only one that has worked. It’s easy to use and easy to clean. If you have an animal that sheds, this product is a must-have." —Jessica Hughes

Get it from Amazon for $23.99+ (available in five colors/styles). 

Promising review: "Best thing I have ever bought for my kitchen. Say goodbye to the heinous noise of slamming cabinets. My mother is notorious for just letting go of the cabinets and letting them slam shut, so before she came to visit I installed these and I couldn't have been happier. They keep the noise to a minimum and likely help to improve the longevity of the cabinet doors by reducing the impact. They are easy to install (although time consuming for all the cabinets in the kitchen) and mine have not fallen off after five months of use. When installing, I pressed them onto the cabinet hard for a 30 count before letting go. I think this is required to make them long-lasting. My father installed these at his home after he visited and his fell off because he just placed them on the cabinets like a sticker. After installing a second with the same method I used, he has not had any fall off." —Dave Carlson

Promising review: "What can I say? It works, and that’s all I expected. It’s about the size of a drink coaster, so it’s not too small or big. It arrived in good condition, with no scratches or anything. Overall, it was a good purchase. My roommate and I always know whether or not the dishes were done." —Jamie Addams

Promising reviews: "This stuff is amazing! I use a Litter Robot for two cats, and sometimes it will stink up the room it's in. This solved the problem! Simply sprinkle some in the dome, then every time the robot turns, a fresh citrus scent is released." —Barb

"Exceeded my expectations. Its non-toxic, natural ingredients are a big hit for me and my feline friends. Thanks to its fresh scent, my home always smells clean! What's even better, it's long-lasting and reduces the frequency of litter changes. The product is easy to use and effective on urine, completely eliminating any unpleasant odors. I wholeheartedly love this item. It's truly safe for cats and does an amazing job." —Loree

Promising reviews: "I got this product about three months ago and haven’t had to scrub my shower since! I just use this every week and rinse it off. It’s life changing!!" —Linds

"I hardly ever leave a review, but this stuff is amazing. I regretted getting glass shower doors until I got this stuff. Sprayed it on and waited overnight. All I had to do was spray the glass down, and it looked the same as the day it was installed. All of the soap scum was completely gone without scrubbing. Will be buying again." —Rebecca Hash

Check out a TikTok of the outlet timer in action. 

Promising review: "I was looking for a better countdown timer to turn off corded entertainment devices after I fall asleep. The one I've been using has small buttons and a LCD display. Although any countdown time can be set on it, the display is hard to see in low lighting. This BN-LINK has larger buttons and knowing their order allows me to select a preset time in the dark. Yes, not infinitely flexible, but 15 and 30 minutes, plus 1, 2, 4 and 6 hours is close enough for my needs." —Picky Consumer 01

Just to be clear, you need an Alexa device for it to work!

Promising reviews: "Not sure how I lived so long without one of these. I am disabled and getting to the light switch is sometimes hard to do but with Alexa, she does the lights for me. I figured she saves me money on the electric bill because I turn the lights off more than I did before. You just tell her the time you want the light on and it goes on. Tell her what time you want it to go off at night and it goes off. Works really well when you’re on vacation, she can just turn the light on and off to make it look like we’re home." —Robyn

"I now live alone and I love that I can have the lights come on when I’m on my way home. Makes me feel safe, and hooking them up was so easy!" —Constance Menin

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

Promising reviews: "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

"I just had to pay $150 for a grumpy plumber to snake my shower. My roommate has long long black hair. Needless to say these work great at catching her hair!!" —Deanna

Promising review: "If you are like my family and keep losing remotes, you NEED this product. I’m going to get these for every room in my house with a TV. Easy to install, and retracts quickly and easily!" —Lauren Hasler

Get a two-pack from Amazon for $9.99 (also available in a four-pack). 

Promising review: "I was able to fit two medicine bottles and a small cosmetic container in there. You can easily lock it around your bed/dresser/etc so no one can take it. It's great if you're living with people and want to make sure they don't get into your medicine/money/jewelry. Great quality for the price." —Kristina

Promising review: "I have been at my wits end trying to sleep with a snoring husband beside me. I've tried foam earplugs, silicone earplugs, etc. Nothing seemed to work. I ordered these on a whim and last night I fell asleep to the sound of waves crashing and didn't hear him at all! The headband itself is comfortable and as I am a side sleeper, I did not feel any discomfort whatsoever. The battery lasted all night, which was a definite bonus. So far, I'm very happy with my purchase." —Marianne Anderson

Promising review: "My wife used this to put out an air fryer fire this evening. It was very scary, and fortunately, this extinguisher was nearby under the kitchen sink. When you see a curtain of flames... the panic is real. I was frozen, but my wife sprang into action with this extinguisher we purchased years ago. I am so grateful she had the foresight to buy it, and I will encourage anyone I can to buy this item. Don't think twice. Just buy it. You'll never look back and be grateful that you WEREN'T prepared for an emergency. Before writing this review, we purchased two more." —Amazon Customer

Oh, and each stamp will last you up to 12 days!

Promising review: "I was sooo skeptical and confused about how they’d work, but the gel solidifies and with every flush, suds wash through with the water and it really makes a fresh difference. Also the scent is light, but really nice and fresh! I recommend these 100%! They’re super interesting, but they do the job." —Janet

Get a dispenser and six stamps from Amazon for $4.67 (available in a two-pack).

Promising review: "Wow! What an awesome product! I was really skeptical, but it worked exactly like it said it would. Such a time saver! After setting off Angry Mama, it literally took me two minutes to clean off the interior of my microwave. Best gadget under $10 I’ve ever bought. I’m so excited!" —ElementaryScTeacher

Promising review: "My roommate left tea spoons and sugar everywhere, which attracted millions of ants. These got rid of the ants in about three days." —Sweetestmuffins

Get a 12-pack from Amazon for $9.58 (available in an 18-pack).

Promising review: "The price is definitely worth what this cleaner accomplishes. I've dealt with cat urine ever since I took in my two trash can kitties. Nothing else has straight up annihilated the urine smell like this did. I've tried so many other solutions on my carpets where my lovable cat loves to 'go'.

My cat also recently 'went' on my roommate's mattress. I drenched the spot in this cleaner and basically kneaded multiple applications into the mattress. No cat urine smell at all anymore. Which, if you have smelled cat urine, you know is essentially an impossible task. Customer for life." —Mike W

It's ideal for doors that are 30"–36" wide. You can cut the foam inserts to fit your door lengthwise.

Promising review: "I live with roommates, and they stay up pretty late with all the lights on while I have to go to bed earlier for work. I used to shove a towel in between the door and the space below, but I bought this and it has reduced the noise and light tremendously! I am so glad I bought this!" —Amber

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: "Definitely helps keep my multi-cat household smelling great. Lovely scents." —Lizzie11

Promising review: "Honestly, I didn’t know if this would work; waiting for it to cool down made me nervous, but once it was at room temperature, it was solid. It popped out of the fryer so nicely. Worth every penny." —Emma

Get it from Amazon for $8.99+ (available in three styles and in multipacks).

Promising review: "I spilled an entire glass of red wine on a light color rug. I thought that the stain would be impossible to remove. Typical carpet cleaners did not make a dent on the stain. I then decided to use Grandma. I’m not sure what’s in this product, but amazingly, it removed the stain completely. I would highly recommend this product. Best stain remover on the market hands down!" —R L

Promising review: "This pretty little lamp is the solution to all candle problems: fire risk, soot on the wall, and quick consumption. I think it makes the fragrance 10 times stronger, and after many hours of use, my candle jar is still full. The timer makes me feel comfortable about leaving it on while going on with life." —Misty

Promising review: "I was pleasantly surprised by how well these work. They were easy to place inside my kitchen trash can and immediately helped reduce unpleasant odors. The scent is noticeable, but not overpowering, leaving the area smelling fresh between trash days. I also like that they take up very little space and stay in place. If you’re looking for a simple way to keep your trash can smelling cleaner, these are definitely worth trying." —KikaBrazil

Promising review: "This is my third robot vacuum and the best by far! I have four kids, twoo dogs, and a cat, so my carpet needs to be vacuumed everyday. This is so powerful. It gets all the animal hair and crumbs that are left behind. I have been wanting to get a vacuum that mopped as well, but was worried that it would ruin my carpet. I am so happy I got this. It mops better than I do. It was easy for me to get this started on the app. I was really worried that it would be hard, but I played around and got it just how I like it. We are going to buy another one for upstairs around the holidays." —Ella
