I’m really happy with my rainsaver. I needed to stop the shed roof runoff splashing against the wall of the house but as it is a plastic shed couldn’t use screw in fixings  The clamp on design of this product is the perfect solution.  I had excellent advice over the phone with regard to what I needed to order, the grippy fabric is an essential extra to the full kit for my plastic shed.  The product arrived within 24 hours and was easy to trim down to size & assemble.  Very happy!
