4" x 4" x 7/8" Pack of 4

I bought them to put under my Midea Duo portable air conditioner, because when it starts up, it creates a really deep sound that shakes the house and rattles plates in cabinets. I tried putting it on a pair of thick wool socks, thinking it may help, but it didn't. These anti vibration pads completely eliminate the problem, and seem to make it quieter all the time.I put them under the wheels of the AC unit, and while it's not the most sturdy, you can definitely roll it off of the pads, they also have no problem staying on the pads if you just leave them there. It would be better with caster cups, but it's fine without them.I heard a lot of people had problems with the smell. When I got them, they definitely smelled like rubber. I didn't test if they'd stink up the room as they came. I left them outside for a day in a somewhat shaded area (the shade couldn't be helped) and then sprayed them down with Ozium. The still smell like rubber, and it's hard to tell if the methods I employed did anything at all, but regardless, they don't smell strong enough to be smelt from a distance.

I can't be sure if it was this that improved my sleep, but I can say that when I combined this with another and put it under the legs of my bed frame, I have felt like I have been able to sleep easier. It did not solve my sleep problems entirely, but I have definitely been sleeping deeper.Although I was still able to feel some vibrations from cars with extremely loud mufflers in the distance (which is the main cause of continually waking up every night, even though those mufflers are illegal in my state), but noticeably less vibration, in fact it has mostly eliminated vibrations when combined with another type under the legs of my bed.I am very pleased with the quality and durability of this item. I would consider stacking several to see if that has a better reduction in vibration, but I would definitely recommend this product as the current price. About $12 or so for 4 of them is a reasonable price, not a fantastic deal, but worth what I paid for it.

Updated Review-Noise cancelation is amazing. Have almost no sound coming from my large whole house Dehumidifier. All noise from my air circulation fan was almost eliminated, air compressor no longer makes itself known in the entire house, dryer exhaust fan is quite to the point we don't even notice it anymore.Washer machine must have internal problems it still walks around and make noise even with just a couple teeshirts inside it. Might be time to replace.Other than that this product perfectly meets my expectations.First Review-The washer and dryer feel more cushioned than sitting on just the hard concreat.Noise reduction was not significantly noticeable. With just the washer and dryer. Going to use the rest on all other noise items. Maybe with my washer and dryer being over 10year old no amount of noise reduction can help them...Still observing will report back once I install under compressors and pumps if the pad help with reducing vibrations and noise from shop equipment.

We have AWFUL PEOPLE as downstairs neighbors. The woman literally pounds on her ceiling/my floor if I just tap a wooden spoon on the side of a pot on the stove, or WALK a little too loudly for her taste. Thank goodness we don’t have toddlers running around anymore. She’d stroke out. Lol - And, no, her husband doesn’t help because he’s apparently whipped by her. I was extremely nervous when we decided to embrace our rebellious sides, and install small, and a very illegal washer and dryer. I bought these square rubber “feet” for both, plus for a spinner that spins at 3600rpm (get that people, seriously. It takes 5 minutes and will cut your dryer time IN HALF. Everyone with a washer and dryer should have one! All of my “no dry” stuff used to take overnight to dry, but after spinning them, they’re dry in about two hours flat, sometimes less!)Anyway, back to these amazing little, magical, sound-erasing rubber feet. We haven’t been reported for our rebel-ness, and we haven’t had ONE boom-boom on our floor from a broom handle, even when I ran a load of “dog puked in the bed” sheets, at 3am one night! They absolutely, 100% cannot hear anything, and our floors are thin! These are sooo great. I’m planning to put them under my sewing table and under the feet of all three entertainment units in our apartment. I’m sure I’ll think of more things too.

For context I live in a second floor condo. I’m using it to suppress vibration from my front loading washer. I have different vibration pads under the legs of my washer that are made specifically for washing machines but I have these lining the floor by wall right next to my washer. It seems to help suppress any vibrations that still travel through the floor boards. Planning on buying more soon for along the floor behind the washer.

Purchased these because my new front load washer is on a pedestal and was rocking and walking, though it was level. The rocking was so bad I’m the machine would not complete the cycle. One of the installers suggested anti-vibration pads. I found these and saw in the reviews that they could manage the weight of heavy machines.1. They do have a strong odor when unwrapped.2. They are strong and lighter than anticipated.3. I like that they’re square. Though it’s not pretty under my machine they work well and my machine completes its cycle.4. Installing them on my own was easy. I could tilt the machine and slides these under the feet with my foot.5 though they are anti slip as well, on certain floors it’s till easy to adjust the machines feet
