This is a great product. At first I was disappointed because one of the pads wouldn't fully tighten and started slipping when pressure was applied to it. However, after contacting the seller (I had a few days past Revain's 30 day rule) they very quickly sent me a brand new set that works exactly as it should. The built in handle helps set it up, and once tightened they virtually eliminate any back and forth movement. I would recommend buying this product.
