First I must praise the fast shipping. Have the shelf ordered on Tuesday and on Thursday it was delivered to me by DPD. The shelf itself may be, after having first unpacked and sorted everything, even without instructions very well assembled. The only thing you need is this a hammer and a screwdriver. Of course, but it is an instruction manual here. But you have to be careful, because the edges but are very scharrfkantig. Therefore, gloves are recommended for safety. But I have worked vorsichitig and therefore suffered no injury cut them without gloves. The one with the sharp edges I do not see as a drawback. Somewhat annoying is the bending of the lugs designed for the center bar, because it's very bad with a screwdriver rankommt. Short explanation: The central struts are pushed into the outer struts with a nose and have to be bent over, so they do not slip out again. But if the first is done, there is also a very stable shelf. To build it took me about 30 minutes. Whether the shelf now actually withstand the specified 175 kg per shelf, I can not say because I have not found anything even after prolonged search that's so hard. :-) But for me, does it make the impression that this is possible. Long story short: I can recommend without restriction shelf !!! LG
