The instructions I found personally a little complicated, after several attempts and curses it worked but then.
The only drawback, as I personally find:
On the product image, the lamp is hanging shown as a ceiling light. In the description, is that it can be used as a table lamp lying. When I opened the shipping box was in it but unfortunately only a lamp socket with a switch and plug it. So therefore, for use as a table lamp, for a suspension did not exist, too, in order perhaps to use this version for the ceiling.
So I'm so then bought another version. So far so good. In the structure description is, one should the cable through the center of a "rosette" (yes, that really is there ...) pull. Unfortunately, my cable of the new version was too thick for it. Did the cable simply pulled through a gap of puzzle pieces that arise during assembly. Thus, the version inside then a bit is crooked, but the lights that falls no longer on! Therefore, a minus point.
Otherwise, the part in the illuminated Zustandt looks really great, better than I suspected.
