Installation is fairly straightforward and the instructions gives two recommended methods. This is not so noticeable once the chair is set back up. They are hardly noticeable and protect my new floors. Glide smoothly on the floor and stay on place.

Now the washer stays in place. Did exactly as advertised, my noisy and rocking washer is now much quieter.

The washer vibrates right off and broke the product. These vibration are not sturdy. A pain to install and increased both vibration and sound.
