Construction was very simple. The items from the package retrieved, assembled according to the enclosed instructions, windows prepared (provided on tilt) and just the shade snapped up at the edge, carefully remove the tape removed, pressed and fixed by the Arritierungsklammern. Done. Quite without drilling and screwing.
Who chooses the other way and works without the clip bracket to the window frame and (probably) used only the adhesive strip without screwing which should not be surprised that the whole structure falls down. This is probably the fault of the majority, who have here expressed negative product. A user error, not a product defect.
I would recommend this product will definitely continue. Certainly there are still some who are still extremely better built and very likely to build even lighter and use them, but to me it is sufficient absolutely at this price and it looks great. The time now is super much light in the room, although it is opaque (if desired). Have decided on the color beige, has been delivered as on the product image (3 pieces).
A tiny suggestion I would have: For the endless chain it would be great if it also would be a weight which biases the chain downwards. Supplied indeed a kind of "safety hook against strangling of children" is included in an adult household but that is unnecessary. The weight on the other hand would have the thing done perfectly round. No need here but deducted a star.
