Your website is not as helpful as it could be for someone ordering one of your products. I ordered blinds to fit a standard Velux which had been fitted with motor after original installation. Nowhere on the website does it mention that I might need an additional part to connect the blind to the motor. You could simply have show. The accessory as “usually sold with this blind if not originally electric window”. As it is when I called Velux they immediately told me that I would need an additional part to make the work. Having waited 4 weeks for the original order I now have to wait an additional two weeks for the extra part. A little thought in the website offering might have improved my buying experience and make me want to recommend the site to others.
