Product review (4 stars): Weak magnet, quality material
The magnetic material backing isn't strong enough to keep the very bottom of the sheet against the dishwasher when it's opened all the way.  It's possible that this is a defect of the shape of my dishwasher & the clearance between the door and the bottom lip when it's opened, but I doubt it.  It's a very standard, base model dishwasher.  It makes the thing look great even though it only covers the door.  It is exactly what it claims to be.
