Product review (5 stars): great for very little investment
These small cups are great if you have your washer on a wooden floor. My washer used to shake the intire house sometimes vibrating things off shelves. Now I can only hear the washer spinning, and hardly no movement in the house. They were a bit tricky getting them installed since my washer is in a confined space. Eventhough the house vibration is deminished the washer itself does shake more, and we had to move the washer away from the dryer to prevent it from banging up against it. A deffinate must have.
