I can not expect much when I gezahle not much. But some errors can be avoided without increasing costs. The metal rod for clearing the nose should look out when complete clean Press slightly to remove the solder residues from the nose. That is not the case. In addition, this metal rod must be front flat, so that it pushes out the solder residues and does not push against the inner walls of the nose. That is not the case, it is simply clipped me the typical chisel-shaped instead of flat top.
However, one can thus still work if you do not want to use it every day. For Hobbybereicht actually sufficient quality for an unbeatable price!
