I owned a Retrax bed cover on my previous truck and it served me well. This is my second cover purchased from Hawaii Truck Concepts going on a new truck. This is a very good product

It would be nice to have a grab bar or a grab strap to push or pull the lid. Otherwise I'm satisfied with the product.
