Product review (5 stars): Stopped the Movement
Although a little difficult to maneuver them onto the feet of our already installed high efficiency washer and dryer [2 person job - one to lift back the machine and one to use a yardstick and flashlight to move the disks underneath the feet], once in place they stopped the shimmying of the machines on our tile floor. Machines now run quietly and do not move. Highly recommend.
