Product review (5 stars): Performs Exactly As Promised
Prior to buying this product, we experienced the same vibration and "walking" problems described in other reviews.  It was so bad that we talked to a contractor about ways to anchor/contain the washer to prevent most of the movement.  He quoted a couple of expensive options, then suggested that we check the Internet for other solutions.

I found Silent Feet on this site and decided to give them a try based on the good reviews and reasonable price.  I wasn't disappointed.  They have eliminated almost all of the vibration and noise from our front loading washer - to the extent that we can even use the faster spin cycles without fear of the thing taking flight across the room.  When I installed them, I outlined the pads with a marker to see how much the machine moved on the tile floor.  They have been in place since April and the washer hasn't moved a hair.

Silent Feet are absolutely worth the money.  And the installation (hate to even use that word since there really isn't any) couldn't be easier.
