This is my second electric tonneau cover and is a much improved version of my previous model. The installation instructions were clear and I have a fairly waterproof system. There were some issues with the installation, such as: 1. the early instructions indicated not to power up the unit until it was completed, however, the integral braking requires power to unlock and unroll the unit (during installation) to check alignment; 2. The canister braces included as a supplement in the instructions have insufficient screws for plastic threads; 3. The remote fob requires button depression at all times during cycling. I would prefer a simple button push for full open or close.
