Product review (4 stars): Somewhat helpful
These do cut down on some of the vibration from my washer.  I guess I was hoping for a miracle. I am now convinced that the particular Kenmore washer I have is just a piece of junk.  It makes so much noise you cannot be in the next room with it and it is sitting on a cement slab foundation too.  This did stop the walking, however. That's why the 4 stars.
