Product review (5 stars): Works - but don't forget the pedestal stand.
Our Maytag front load washer with pedestal stand is located on our first floor on top of a vinyl covered wood floor with a walk space underneath the house. When we first got it I was surprised at how noisy and how much vibration it was producing when running. This being our first front loader we were not expecting this. As time went on (about 3 years) the vibration and noise seemed to be getting worse as the wall in the living room (about 14' away') was vibrating to the point that a wall decoration was shaking and the machine itself started walking from its original location about 3-5" every time we used it, something it did not used to do, and yes, the machine was level.

Before installing these feet, I pulled out the pedestal drawer as far as it would go then removed the screws (2, one on each side, at the very front of the slider holding it)and crawled into it's opening to check the bolts holding the pedestal in place.  Sure enough, some of them had become loose. Tightened them up and installed the Anti walk feet using a crowbar and a block of wood to lift the back of the unit one side at a time. We have no space on the sides in which to reach the back without pulling the washer all the way out and all the trouble that entails. The front was much easier of course.

Bottom line is that now, even after 4 loads we do not notice it running. It makes more noise when the water is filling it up then when it is actually going from one cycle to another. It still vibrates (a lot less than what it was doing) but the feet are absorbing this without a problem. It has also stopped walking across the floor.
