1" Sorbothane Hemisphere Rubber Bumper Non-Skid Feet with Adhesive 50 Durometer - 4-Pack

Got these to put under a set of amazing little Pioneer BS-22 bookshelf speakers that came without feet. The 50 duro sorbothane is quite squishy and sticky; the labels warn that the plasticizers may attack certain materials, and I believe it. You'll want to put them on a hard and invulnerable surface; I set the speaker on an old LP album cover and the feet started getting glued on within a day. They will definitely not let whatever they're attached to dance around even under extreme vibration, as they're very tacky.You'll want to be aware of the weight rating for your application. Mine are perfect, in the mid-range of their rating, but they do squish down and deform some and I would not want to overload them.These seem excellent at reducing vibration, and I'd love to do some measurements, but I won't, honestly, because I am lazy. Maybe you could, if you have the time, equipment and inclination. For my purposes, they make great speaker feet, and hopefully de-couple the bookshelf speakers from the unfortunately resonant bookshelves they're on. I wouldn't put them under something very tall and narrow and top heavy, like a floorstanding speaker, because they are quite soft and might make a tall thing unstable. Kind of expensive, but cheaper than many other squishy sorbothane isolator thingies, and nicer than regular furniture feet, so I bought 'em and I'm happy. Like the effect of a Riedel glass on a fine wine, they improve my experience because I expect them to, if nothing else. Ah, I do believe my speakers sound better already.

I purchased these as a last ditch effort to isolate 3d printer vibration/noise. It sits on a built in desk that basically turned the wall cavity into a sound amplifier for any and all noise/vibration created by the machine, it was horrible.I started with neoprene foam dampening sheets; they helped a bit with the general noise, but by no means silenced it. They didnt satisfy me. Next I added some anti-vibration pads intended for studio speakers and light industrial applications; same effect as the foam, still not happy. Then I went as far as adding acoustic wedge foam to the space, which improved the general print noise, but made no difference to the sound created by the vibration.Finally, I ran across these on a forum from a google search, and they are the HOLY GRAIL. Full stop. Immediately upon slapping these puppies on the feet of my machine; silence. Even when I crank the speed way up you dont hear a peep. I can now print through the night without annoying the whole house. Im honestly just amazed and will be using these for any and all applications where Im fighting noise/vibration.READ THIS NOTE: This is not a general, catch-all product; This is engineered to work in specific weight and size ranges. Would you put a passenger car tire on a semi-truck? No, of course not. Same idea here.READ THE DOCUMENTATION! They have a nice and simple table on their site that allows you to pick the correct size and duro rating for your application. Also note that these are NOT anti-slip pads or something like that to keep your washer from walking; Thats not their intended use, so they're obviously not going to stay stuck on. The 3M adhesive back is perfect for its intended use.Overall, an absolutely excellent product that Im happy to pay good money for, and will be looking for excuses to use them on other things.

I wish the glue on these was better. The rubber bumpers are very grippy, so if you use these as feet on something, they will slide off with too much (or really any) friction. It's not the end of the world, and they are very nice otherwise.

I have a digital-to-analog converter that produces outstanding sound through 8 channels. It has tiny rubber feet seem too hard and too small to absorb vibrations. I replaced the stock feet with four of the 1" Isolate It! feet.I can't tell the difference in the sound but I do know these feet are providing more vibration protection than I had before. This makes me feel better about the long term prospects for my device.An additional benefit I didn't consider on ordering is that these new feet raised the device maybe 3x higher than with the stock feet. Now, it has better heat dissipation as the air can move below the device.Yet another benefit I didn't expect was that the feet are tacky and secure the device in the exact spot I place it.All in all, great product. Can't wait to use the bigger feet on subwoofers and bookshelf speakers!

Total garbage, very expensive. They work OK for about 6 months.Then they become squishy, compress to nearly flat, ruin to surface on which they are placed and stop working as isolation bumpers. Do yourself a favor and stay away from them or get a different brand like Hudson Hifi - which after 3 years are still as good as when I bought them without any damage to my furniture.

Ok, so I purchased these rubber bumpers for a slightly unconventional reason. I bought tilt legs to apply to the bottom of a new laptop. Well, these legs work great when "deployed," but they totally screw up the balance of the computer when they are not deployed--and the computer tips backwards when the screen is open. So, I figure that if I got something to balance out the bottom, the problem would be solved. And, boy howdy! These babies did the trick. I don't have to deploy the tilt legs if I don't want to. Plus, the hemispheres add an extra level of "non-skid" to the bottom of the laptop.The adhesive on the hemispheres is pretty good...even for a purpose for which they were not meant. But, you should really make sure that the place where you apply the product is clean (maybe a swipe with rubbing alcohol). In my opinion, the adhesive takes a while to "set." Leave them still for a couple of hours.I will definitely order these again! Expect an update on the life of the adhesive :-)
