This has been an awful experience. I bought the product in advance of some renovations. The package was somewhat damaged but I did not think too much of it. When I when to install one of the red securing tab was loose. Again I didn’t think too much of it. When I mounted (second one I’m installed) the blind was detached from the main power unit. I unmounted and failed to put it right. It is now an expensive waste. I’m now familiar with the design and certain the bind became detached during transit due to damage/dropping of the box.
