The operation of the frame is good, but the material and the processing is significantly less valent, as one might imagine it to the photos so. The frame is made entirely of plastic. The moldings are produced accurately and he was fully assembled and ready, but I had hoped for wood. One can only hope that the screws will hold well after some adjustment yet. What I do not like is to secure the chain. This one should stick with scotch. That's a somewhat s ***** owned facility, since there might be better and I have to think about how I can modify the frame. I had wavered between 3 or 4 points, but then have him 4 given, since the operation in general is quite good. So far, the chain also has sufficient voltage.
