Product review (5 stars): Great Product!
We have a front load washer on the 3rd floor of our house.  The washer wasn't walking on the spin cycle, but we could feel it vibrate the house.  After installing the Silent Feet,  we could hear it go into the spin cycle, but could no longer feel it!  The installation was very simple (other than having to climb behind a very heavy front load washer which was a great job for one of my kids!)  I am on my third load of laundry since installing them and am so far VERY happy!
