Product review (5 stars): Check the housing before buying
As others have said, DON'T BUY THIS UNTIL YOU HAVE CEANED OUT THE HOUSING.  I was about to order this but read the reviews and, instead, pulled the lint trap and took a peek inside the housing.  It was full of compacted lint that was causing the trap to sit up and...snag and tear up our clothes.  A few minutes with a wire coat hanger and vacuum and voila!  The trap seats perfectly.  Save yourself the $20.
