Review on M8-1.25 Anti Vibration Rubber Isolator Mounts With Studs Shock Absorber by Dan Weeman

These vibration dampeners are fantastic. I recently installed a mini split unit and had to mount the compressor to the wall outside. When the fan turns on it hits a harmonic frequency that vibrates the inside wall just enough to where it sounds like a large truck is idling outside. The vibration was driving me crazy, I tried numerous dampeners to try and eliminate it and none worked as well as this. I installed these yesterday and it has completely eliminated the vibration that was transmitted to the house and no longer makes a sound.Previously I tried cork, foam, and hard rubber dampeners, but none worked. As an extra layer of dampening I put a few rubber washers between the metal washer and the bracket for the compressor. I would highly recommend these.
