Product review (5 stars): They really work!
I have a second floor laundry and a front loader washer. After the placement of these wonderful "feet" I no longer have a vibrating floor and clanking chandelier. I would absolutely recommend these to anyone, and as a matter of fact, I installed them on my dryer and bought them as a gift for a friend of mine with a Bosch front loader. I was a bit surprised how well this simple fix works. The product is as described; if you have a walking washer or a second floor laundry don't expect a miracle, but hopefully you will experience a dramatic improvement in the vibration.
