Product review (1 stars): Waste of money
I purchased these anti-vibration pads subsequent to my purchase of an Electrolux front loading washing machine that shook the whole house when spinning.  My hope was that these pads would solve or at least mitigate in some way this vibration problem.  I installed the pads as instructed, balanced the machine to perfection horizontally in two planes and ran a wash cycle.  Much to my surprise, the vibrations were worse than before!  The pads elevate the machine from the floor and, in effect, move the source of the vibration further from the floor.  This creates a more unstable situation than without the pads.  Buyer beware.
