Product review (5 stars): Works as advertised
Our washer is on a first floor and sits on a tile floor made of duracermaic tiles.  The floor is not perfectly level, probably due to the washer vibrations, so it is very hard to keep the washer level at all times.  Before this product our washer would walk across the floor only to be stopped by the wall in the laundry room.  I researched multiple ways to eliminate vibrations and walking.  I learned about screwing plywood into your flooring which I refused to do in a brand new home or reinforcing the flooring joists by putting more braces in.  I also researched a few similar products before settling on the Anti-Walk Silent Feet twin pack.  Prior reviews are what sold me on this product.  This product works great and I would recommend it to anybody who has vibration or walking problems.  It eliminates 90% or more of the vibrations and also keeps the washer in place with it's sorbothane material which holds these pucks in place.  The noise reduction is also amazing!  Others who have rated this product poorly either have not followed instructions properly during set up or they have an extrememly unstable floor that their washer is on.
