Product review (5 stars): Exactly what I needed!
Laundry room is on the second floor of our new home.  We bought the biggest and the best front loading washer and dryer, of course no vibrations in the showroom.  These machines were actually starting to crack our drywall! Have been trying to figure out a solution to our vibration issues for the last two years.  These little rubber feet actually work.  We love our washer/ dryer and even our house again.
