Product review (5 stars): These are amazing!
I purchased these Silent Feet (red package) with a bit of skepticism after reading some reviews that said they didn't work; however, I opted to tr them anyway as I was sick of having to push my washer back into place after every load.  It would walk about 6 to 8 inches every load.  I never had a problem with this machine until we moved into a house where the laundry room is on the living level - not in the basement.  What manufacturers and store salesmen don't tell you is that these front load machines are designed for concrete floors.  In addition, putting them on pedestals only makes matters worse.  I only found this out after having a repairman come out to check it for excessive vibration.  In desperation I tried the Silent Feet and I am ecstatic!  I have been using them for about a month now and the machine has not moved at all!  Not one inch!  I HIGHLY recommend this product for others who have Walking Washers.
