The material quality is fine, it fails to detail. For example, the upper bracket is only intended to be mounted above the tile panel. I had real trouble, the vertical tube to be mounted vertically. Even shortening the insertion part by 1 cm and thus gained to the stop did not bring the complete success. The pipe is up more from the wall than the bottom. Another gripe is the grub screw to fix the valve member on the attachment piece. Could not attach offset by 30 degrees this screw? Man it would be much easier with the attachment. The fact that I had up too much distance from the wall to the tube, and the lower flange was not going to get tight. I had to cut the already mentioned 1 cm in order to achieve a straight flange connection and thus tightness. As part of this adaptation work I had to solve the valve piece of the mounting base and tighten a few times. Every time I had here may strangle the Kontrukteur this system. Apparently assemble these gentlemen never even once such a part. Because then they would realize the weaknesses.
