Product review (5 stars): They work!!
My washer is on the 2nd floor and sounded like we had a helicopter landing on the roof every time it went through the spin cycle. It never walked or anything, just was SO loud. We put these feet on and I watched it the entire first load. Throughout the whole cycle it looked like it was jiggling a bit, which it didn't before. I got really really nervous it was gonna fly through the wall or something during the spin cycle. Spin cycle came around and I was amazed. Yeah it jiggled a little bit but it was super quiet and the floor vibrations and noise were cut down probably 90% and the stuff on the walls doesn't rattle anymore!
