Product review (2 stars): Product did not work for me
We converted a bedroom on the first floor of my home into a large laundry room.  This room was directly over my son's room in the basement and I was concerned about the noise of the washing machine on the tile floor.  I purchased these before the room was completed in hopes of keeping the machine quiet.  Unfortunately I didn't consider the fact that I have a top loading machine with a lid that opens toward the back.  The added height of the silent feet did not allow my washer lid to open fully.  I sanded down the bottom of the cabinets, but still pinched my fingers opening the lid.  Also the silent feet actually increased the noise during the spin cycle because the washer would bang into the dryer sitting next to it.  Luckily when I removed the silent feet which left black marks on the floor, I had no problems.  The washer then had lid and finger clearance, my machines never move (they don't walk like some front loaders) and they no longer bang into one another unless there is a really unbalanced load.  If you have a front loader that tends to move, these may work perfectly for you.
