I was wary that this retrofit blind might fit badly or be difficult to get in. In fact the manufacturing tolerances were fantastic - worked like a dream - to fractions of a mm accuracy! Very impressed.
Just need to take your time and a bit of thinking about exactly what the instructions / pictures are telling you to do.
We tried a cheaper non Velux blind for one window which was no where near as good! Velux seem expensive but they are worth it !
Customer service agent Sam was friendly and helpful. She made a note and carried out amendment to order when it transferred to system as promised.
I was replacing old blinds and found the process straightforward. I’m delighted with new blinds.
I needed to find a non velux video on YouTube to help explain the removal of the old blind. The old blind had only been in place for about 3 years when it had to be replaced.
