Product review (5 stars): Great for second floor laundry room!
These really work! I have stacked front loaders in our second floor laundry room and every time the washer was on the spin cycle it would shake the second floor of the house like crazy. After installing these the vibrations are much better and most of the vibrations are absorbed into these pads. I was getting worried about damaging the structure of the home and having to move the laundry room (which I didn't want to do because of the convenience of it being in the second floor) but now things are much better. I highly recommend these especially to anyone with front loaders on the second floor.
