Most things on the stand have been already said and I can also confirm. What, however, about the causes me this assessment, the fact is that after about nine months use of the riveted head was loose without that I would have overturned it, extreme stress or something would have made it (except of course a camera or flashes on to assemble). Cullmann service contact, problem with the rivets is known there, and the center column was exchanged without difficulty and quickly. Since I am still convinced of the magnesite 525, there are three points - deducting course for the loose head, the fact that the consignment is not accepted carriage forward and that on the website of Cullmann no evidence can be found that their products (at least the magnesite 525) are made in China.
