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'm a sound engineer recently got an apartment in the last floor in 8-floors building and 8 big AC machines exactly on the top of my apartment, the low frequencies and vibrations were passing through the ceiling to all the rooms in my apartment, even with the cork pads installed originally by the contractor under each machine. I've tried installing sound sheets with 50mm cork panels, but this didn't solve my problem, actually made it worse. Finally ordered these pads and cannot imagine how big the difference is between them and the other cork pads, these have solved the problem almost 90%. I still hear a verrrry little low frequencies with NO VIBRATIONS AT ALL. but cannot confirm if the last 10% noise are coming from the same 8 machines I worked on or some other far machines on the roof. I highly recommend these pads, you will never regret buying them. I'm going to order again to try adding another layer or put on other far machines. Thank God I found them.

These are very sturdy and dense pads. They seem of very good quality. I will say that these did not work for my application, but I have no doubt these work for the intended application. Due to their density, these will not reduce low frequency, high volume vibration such as I tried to use for my desk at work with how shaky the floor is. These would work well for damping high frequency, low volume vibrations such as an air compressor or other industrial machinery.

I recently moved to an upstairs apartment. I have a portable LG all-in-one front loading washer/dryer. I bought it on Craigslist used 12 years ago. It works great. It washes and dries like a champ. Except... I had never tried to use it in an upstairs spartment before. Even though I had carefully balanced the machine, my powerful washer felt (and sounded like) like an earthquake when the spin cycle was on. My whole apartment including the walls shook. 🫨 I purchased and tried a couple of solutions to try to reduce the vibration and noise but they really didn't do much. However, happily, I tried these pads last night. THEY WORK!!! No more earthquake. My neighbors won't hate me. I have seen similar pads to these for 3 times the price and didn't really want to spend $40+. Now I know I don't need to. I highly recommend these pads.

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.
