Product review (1 stars): Best thing ever, if you want to knock down a wall
Waste of money! Not only did it not reduce the vibration of the washing machine it actually made it worse. I believe the issue is with the consistency of the rubber being too soft. As the machine vibrates the rubber pads act as a trampoline increasing the  overall motion of the machine. I took them back off of the machine after only 2 cycles. Guess I will have to find some other use for them.
