Product review (2 stars): Works, kind of...
Says it's made for the Whirlpool Duet, but the holes do not line up on the machine.  Not even close.  I had to mark and drill new holes in the back of the washing machine in order to get it to work.  Fortunately I had the tools to fix it.  Once new holes were drilled it went together fine.  I wish the dryer didn't sit so far back on the washer.  There is really no reason for the washing machine to stick so far out...
