Product review (3 stars): Waste of money
Made with a brittle plastic.  We have a 'one piece' stacked washer/dryer, too much weight to lift and slide this under.  Tilted it back, slid this under as far as we could, and had to lower the washer back down, and the plastic pan cracked to the point water leaks would not be contained. Waste of money.  It would probably work fine if you can lift the washer up and slide it all the way under.
