Product review (5 stars): Work perfectly!
Got my new Electrolux washer and dryer. Bought stack kit so they are connected together. Did first wash when I came back to put clothes in dryer the whole unit had moved and my ventless dryer water condenser thing had slid out of its slot (glad it did no damage).  Before my second wash I put the pads on bottom of washer when I came back washer/dryer did not move. These really work.
