The roller arrived on time, and everything was in good condition. The instructions for assembly were a little vague, the sections of tubes fit together nicely, but the hardware, and screws could have been better quality, so that everything stayed together. I’m sure there are some tips and tricks, depending on the application, the dimensions of your pool and surrounding surfaces, but until you build one, you just don’t know. If I had to start over, or put another one together, I would make it a little bit wider than the actual solar blanket, at least 12 inches, that would make rolling and unrolling easier, and if you’re doing it in a strong wind, it wouldn’t bunch up too much. All things considered, I’m happy with it, and glad to finally have one.
