The only criticism I would make is that the pictorial instructions lack detail for connecting the power cable between the frame and the window. I assumed that the instructions were to isolate the power whilst installing the blinds and as my installation includes isolators for each window I used these. I was somewhat frustrated when the blinds wouldn’t connect to the remote control. It was only after I climbed up onto my roof that I realised that the cables were not connected. Why isn’t this done as a matter of course during manufacture or installation? Once connected everything was so simple.
