Sky Fit -Easy to Fit? Installation instructions were unsuitable for my use. Had to figure it out myself. Correct fittings were supplied but not mentioned in the installation video. Pre-drilled side channels would have helped. It was difficult to ensure the holes were central to internal moulding which pulled the channel out of line if not correct. Blind tape take-up drums were not correctly aligned- a long way out in fact - I had to dismantle and correct it myself. Somfy electric motors are great. I already have had 6 in use elsewhere for a number of years. Can't fault the SkyLight Blinds sales team.
