I purchased this a few weeks ago and I'm very happy that I did.  The washer and drier are much easier to use now that they're elevated, and towels or bigger clothing no longer drag the floor when switching into the drier.  

The measurements are very exact.  We had 1/2in clearance between our cabinets and units based on the math and it was spot on.

My only complaint is it's very pricey for a drawer and stand.
