PneumaticPlus 4 Pack of Anti Vibration Pads 3" x 3" x 7/8" Rubber/Cork Vibration Isolation Pads

After contacting the producer he has been very helpful and he sent us back the product for free.

Compré este producto para usar como bases para una hidrobomba en el techo de mi casa. El ruido y vibración son casi nulas ya que la bomba anteriormente vibraba con el concreto del techo. Ya no es necesario taladrar para fijarla. Maravillosa solución. Nota: Tiene una etiqueta que dice que el caucho continene plomo. La mayoría de los cauchos industriales lo contienen entonces manéjese con precaución y de recomendación en exteriores.

I am using these to quiten an external drive with a bunch of HDDs in it. These do help the sound from traveling through the floor as loudly but not as much as expected. I am not 100% convinced they were worth the cost.

Having bought this product to isolate from the floor, a couch which has a 100Watts (rms) bass shaker bolted to the frame and I am very satisfied of the end result. The sound vibrations aren't transmitted to the walls and surroundings anymore since I fitted every couch support with this product thus doing exactly what I expected. Therefore, I cannot speak for other purposes but for those looking to isolate audio equipment, subwoofers, speakers, bass shakers... look no further. Great price/performance ratio for audio acoustic isolation purposes

Actually removed the vibration noise from my 3D printer~

Realised product very small shortly after I ordered, but was already too late even if the delivery was scheduled in a couple of weeks. Cancelled but order arrived anyway and practically impossible to return, so check properly before you buy! I didn't have a chance to try if they actually work because too small so useless addition to my garage.
