Product review (5 stars): Really keeps my front loaing washer from moving on a slippery hard wood floor.
They have solved my washer from moving across a slippery hard wood floor.  It's very important to take time and position the feet accurately the first time since you'll probably want to stick them to the floor.  One hint...use double stick tape on the bottom of the washer feet so the anti-vibration pads can be properly placed the first time.
