So, you get a lot for your money, but if the diagonal would be measured from the roof from corner to corner, only 0.5 cm greater, even then would be due 5 stars! So far 2 times up = 2 corners torn; So can build even 4 times, and then? I thought, so the story would be finished, but I was wrong: First, an apology was placed via email (I was fine) and also offered a free replacement (which I accepted, of course). Today was delivered !!! I was curious and have equal unpacked and set up; Result everything was fine !!!! Then I lifted the review but equal from 3 to 5 stars (more is unfortunately not possible). Great management, great service !!!
