Just one minor issue - The \"side guides\" instructions show 6 x pre drilled holes (3 on each side guide) and there were 6 x screw provided, however, there were actually only 4 x pre drilled holes on the physical side guards (2 on each side side guide). It hasn\'t prevented the overall installation of the Velux blind, but I\'m not sure if this will cause any issues at a later date.
