Product review (5 stars): Saved Our Marriage
These vibration dampening feet significantly reduced the noise that our new Samsung washer and dryer made while sitting on a wooden floor.  (Don't ever put your washer/dryer on anything but concrete.)  While it took two people to lift up the machine and get the "feet" underneath, it was doable.  We took the advice of others and put the dryer on feet too so that the machines where at the same level.  The feet are barely visible and the washing machine can now spin without making the house shake.
