Once after a long wait eintrudelte the package, were only tested at all any joint pieces contained. Unfortunately had to be reworked at all things, as remnants of the spraying process had not been removed and thus stubbornly set in their way. The screws have to head to a slight degree, but this disappears after a few meters in the working thread. I conclude that it is very hard-wearing plastic. I have used except the pipe clamp still none of the package contents because the original but a lot are smoother. Totaly recommended just for the price, unlike the original accessories, however, especially if the GHalterung is used only occasionally.
