The window electric blind is ok and reduces radiation heat from the sun. However the picture booklet instructions are inadequate. It was not apparent that the electric velux cable for the blind is stowed out of sight. It only became apparent how to find and connect it after watching an independent YouTube video. Once connected it was a struggle to get the remote to work. It required a lot of resetting. Still not sure how it eventually worked. Both blinds have wrinkles down one side. Hopefully these will disappear over time.
