Installation of the blind was a pain. The connections for the frame and the side rail blind driving pins were not very tight and kept coming out. The frame appears to be mainly held together by the tension of the driving cord. When moving the frame it is easy for it to separate enough for one of the motor shafts to disengage. When first assembled the blind only moved about 30cm. Fixing this may have been covered in the "Motor Setting Manual" but this is difficult to make sense of. In the end I drove the motor until it stopped before installing the drive shafts and this worked. On a positive note the people that I dealt with in the UK were very professional. It was not however made clear until after order that the main blinds are in fact manufactured in Dubai! The installed blind looks good and I hope that it lasts
