1" Dia Sorbothane Hemisphere Rubber Bumper Non-Skid Feet with Adhesive (8, 50 Duro)

They make my $5 cinder block stands sound way beyond many best buy ones. Maybe not high end audiophile, but definitely lofi/midfiGreat value for the money

Excellent product. I use these as replacements for pads on the bottom of the feet for vintage turntables that I am restoring. The original feet are often dry rotting and getting hard. These are much softer and provide far better isolation from vibration that the originals. I have also used the pads as outright replacements for the original feet. They are a solid tweak or upgrade. If I had any complaint it is that the protective paper backing is difficult to remove. Perhaps the manufacturer should consider pre-slitting the backing so that they are easier to remove.

I used these to reduce vibration noise from a blower fan under my gas fireplace. The blower weights about 8 pounds. I one bumper used for in each corner of the rectangular foot pad. Killed the vibration sound completely. Was very easy to work with.

The rubber bumper is a nice soft supple material that is good at isolating vibration and does not skid. However, it is really sticky. I place 4 of these feet on each of the tongue drums I built. The tongue drum is essentially a box with tuned tongues in the top that vibrate to produce musical notes like a xylophone. I wanted to isolate the vibration of the tongue drum from the table I had the drum on. However, while the rubber feet do a good job of isolating, they are so sticky that it takes quite a bit of force to remove the tongue drum from the table. In fact, each of the rubber feet actually pulled off the finish from my table so I have 4 round spots on the table where there is no finish. It ruined my table. Additionally, a couple of the feet fell off because they stuck to the table more than the adhesive stuck to the tongue drum. I'm not happy with this product.

The product works better than expected. I had quite a noisy 3D printer. Now I am able to print at night, sleeping in the next room.

Should have looked up "Durometer" before purchasing. I thought these 1" feet would be oversized for my bookshelf speakers but they're squished nearly flat because of how soft they are. Not sure if that's the desired effect or what, but it seems to me that using four larger 70duro pads would be more appropriate for my 11lb speakers.By the way, I hear no difference in sound between using these and the pink rubber erasers that they replaced. They're fine I guess, but I knocked a star for price because I fail to see what all the fuss is about.

These little things are like magic. If you think you can just buy some little rubber pads at the hardware store and get the same effect you're not giving these the credit they're due.I bought them because I just moved and ended up in a position where my A/V receiver and Directv DVR needed to sit right above my subwoofer. I build high performing subs occasionally as a hobby so I knew with this one the vibration would not be good for these components if I dared set them on top of the sub itself. My options were a wall mount component shelf to separate the components from the sub or to try these little guys out and set them right on top of it. At this price I gave them a shot and they have not disappointed. Four pads on the receiver which sits on the sub, and four on the directv box to sit on that. I can set my hand on top of the two while the sub is working and basically feel nothing. 5 stars for my application.

I stuck five of these on the bottom of a rack mount power amp that now sits on a shelf. It’s an older type D-75 Crown, and I used one at each corner and one extra on the side where the heavy transformer adds more weight. They seem to work well and the amp runs cooler for getting some air below it now.
