Product review (5 stars): Worked as described, solved a real problem
My front-load washer (raised on attached pedestal) is perfectly level but it was "walking" several inches across the tile floor during large loads.  It is installed in a tight space and the movement was causing annoying consequences like blocking the doors, hitting the pipes, etc.  I put the pads under it and the problem is gone.  Last night I watched a big unbalanced load shake the washer side to side like a tower in an earthquake, but the feet did not move a millimeter.  Things are quieter too now.  Great product, well worth the price for me.
