Product review (4 stars): Does what it is suppose to
Had a tight spot for a dryer and needed space.  Purchased this product to get a little bit more room.  As one review stated, one you get it on, and sealed with tape for the gaps, slide the dryer back and do not move it again.

It was a little difficult using a clamp for the part that connects to the dryer.  This was more due to a tight space that I had.
