Product review (4 stars): Only Somewhat 'Silent'
These anti-vibration pads were placed under our new Bosch Vision 300 Series washer because, when it spins dry, the pots and pans in the kitchen cabinets (kitchen adjacent to laundry room) rattle noisily and the floor radiates vibrations for about 20 feet.  (Note that the washer and dryer are on a tile floor in the laundry room.)  So the pads certainly do not eliminate the vibrations; they do damp them, however.  I would say that, if you have serious vibration problems, as we did, this is a worthwhile investment, but do not expect that the vibrations will be eliminated.
