Product review (5 stars): Fantastic product
This saved my sanity and my washing machine.  We've had a front loading HE machine in a second floor laundry room for a few years now.  Everytime it was loaded with something heavier than baby clothing, it would shake and vibrate half the house.  It was so bad that it cracked some of the plaster in the room next to the laundry room.  I was considering selling the washing machine and buying a top loader, but decided to give these a chance first.  After installing the feet (took just a few minutes, would have been faster if I had someone to help me) I loaded the machine with some jeans to see what it would do.  This has COMPLETELY eliminated the house shaking.  I highly recommend to anyone trying to solve this problem.
