Ordered a black out blind for a GGL-1 Window. The blind fit in place perfectly however we were not supplied with the tabs the blind snaps onto at step 1. We have an older Velux window so expected something to go awry. With a bit of improvising it fits right in place. Delivery date was confusing as we recieved an email stating a certain delivery date. But it arrived at a complete different date and time than planned.
