Product review (5 stars): Very efficient.
Worked very well for me. The washer (Samsung front loaded) used to turn slightly after every use. After I have installed Anti-Walk Silent Feet it has not moved at all.
One piece of advise for those whose washer is installed on a pedestal in a tight location without access to the sides. It turned out to be much easier to install the feet by first removing the drawer from the pedestal (unscrew the screws holding the drawer to the rails and slide it out). After that there is enough access to the feet from the front. You'll need a couple of extra hands: one person tilts the washer slightly while the other inserts the feet.
