Product review (5 stars): Anti-walk Silent Feet saved my back
Have an HE front loader that I'm really happy with.  No real problem with vibration that I've noticed.  Only problem I have had was when doing a load of towels.  The machine would decide to moon-walk across the floor and I had to push it back into position after every load.  I decided to buy the anti-walk silent feet to see if I could curtail the machine's forays into spaces in which it did not belong.  These feet work great.  I have done large loads of towels after installing the feet on the machine and it has not moved one inch.  I am very satisfied with this purchase and would highly recommend trying these if you have similar problems.
