super blind, I do not know what some people have here for trouble. possess genuine VELUX blinds and now this. entscheident was the price, why pay more when you can have aluminum for good money. have the blind in a VELUX Plastic windows installed and unlike some hierdie nipple of the cap for the blind original not canceled. rubber wedge and pry gently make it possible. well I do not find it particularly difficult 12 screws easy to drill and screws before using a phillips twist. which seemed fit to 100% and must not be edited or hanky pure. Unpack the whole thing with, pre-drilling, screw caps and original abnhemen takes max. 30 min. !!! the blinds look damn classy with the aluminum rails and can really be set in any position and the penalties fabric. this does not stem times without a slight wave my original VELUX blind. the blinds are dark to 98%, a very minimal light slit has aluminum frame at the top. can the blinds only recommend and have me directly the next just ordered for my GGU M08.
