Product review (5 stars): STOPPED VIBRATING WHOLE HOUSE
SIlent Feet did just as promised.  We have an LG front load washer and dryer and the washer would shake floor joists so violently that you could feel the floor move all over the house.  Vibration is gone and noise level is cut to minimal.  I use to wonder if our house was caving in every time I did laundry...now I forget to check on it because it is so quiet.
