So the assembly is very easy and whoever does not have just 2 left hands gets even without assembly instructions back. (Had the assembly instructions only not found, it is in the little box in which the "small parts" are). Have the variant used clamps and gluing, simply tilted window, the holder glued at the right distance and hooked the terminals, windows closed. That was in Prizip already. Clicked rail with the blind on the holder and then pushed the roll holder in the window holder and the shade attached to it. One should be careful to ensure that the part on which the chain is, exactly is in the balance, otherwise it hakelt a little while Rollo pull up (but can also be subsequently corrected). The appearance is simply unbeatable. Also have the blinds bekommen.- also in the ordered me Colour So for me there is nothing to complain about, so even 5 stars.
