Why did you pick this product vs others?: Cost and form were right for my application. Ease of installation: Very easy to cut, peel and apply to surfaces. The 1”x1” grid on the peel-off backing was particularly helpful. Works well: I used it to reduce the noise of my dish washer by lining the walls and top of the under-counter space where the unit sits. I didn’t take before / after noise measurements, but the sound reduction is significant.

Used on the bottom exterior & interior of an indoor fountain (sits on tile) to help mask the hum of the pump. Not gone but definitely reduced, and the pump noise is now less than the water noise.

I live in a house rental in a decent neighborhood where the noise levels are generally quiet... except for the fact that one of my neighbors keeps their poor dogs outside most of the time. So those dogs yap a LOT at anything and everything. Since then, I have used a compressed airhorn to train them to stop barking due to their owners being lazy. That has worked really well, but when I am already in my upstairs bedroom - preparing to go to sleep - I can't run outside with the compressed airhorn and blast it in their dogs' faces while indecent - and blasting the compressed airhorn from my bedroom window is ineffective unless I go directly up to their fence to do it. So I purchased three of these products (not cheap, I know. But my sanity was on the line), and just stuck them as best I could inside of my bedroom's window frames, then used acoustic sealant to fill in the gaps. I'm now able to finally fall asleep and not get woken up in the middle of the night without even slightly hearing the dog barking. The acoustic sealant isn't very rent friendly, but we got to do what we have to do to protect our peace. *shrug*

Adhesive is horrible. Keeps falling off the wall. And does nothing to reduce sounds.

Purchased this for sound equipment, once applied, it shrunk. Very adhesive though, which is nice but just wish it stayed in place.

Rxcellent product

I used this to put around the motor and part of the piping of my radon mitigation system to suppress the constant annoying hum I could hear in the room closest to it. This stuff did the trick. I can barely hear any sound from the motor now. I will have to wait and see how it lasts, but it did have an immediate effect. The adhesive was very sticky and adhered well to the motor housing and plastic pipes. I did take the precaution of putting on some electrical tape to hold it in place just in case the adhesive starts to loosen. If the material doesn't last, I will update my review, but for now the material couldn't be doing a better job. I would recommend this product and would buy it again if needed.

Really functional! I put them on the side of a loud mini fridge a couple months ago, and they seem to be holding strong except for the corner at the top, wanting to lift a little bit! It’s made a significant difference in the level of noise and I don’t worry about the heat of the side against the wall as much.

Très bon produit et colle très bien

Its ok, quality is good but cannot really say that it does block noise in the Pipe

Just don't buy it, it doesn't work.

Highly recommended for repairs
