Holder labile and cheap - charging cable okay

bad:
The holder is quite labile and made really cheap. You can not install the center tab, since then the volume is pressed permanently. It wobbles pretty when driving. On uneven roads is no longer easily read it. The hammer is that my part does not match the one displayed here. It is still unstable and has no metal ball forward. The part with metal ball I once had a short, but it had to return because the suction cup mount is too small and the outside had a small notch and stopped the disk only max. 1 Minute. The next bad news is, that comes with the bracket no packaging or documentation. Ie you can not at all check the delivery extent it corresponds to the (no., Etc.), what you get delivered out here with the pictures, which do not vote yes. Had I read the reviews before 2 my order, I would certainly have taken a part andres. Whether I would be happier with it, but I do not know either. Is indeed much today Gruschd somehow ...
