Holder works all winter and spring on properly! I did not need to turn Allen! The connector for charging is good actually nothing! But what do people expect here at such a price ??? I wanted a holder and no charging cable! So in the foreground the holder! This has been resolved with the first rays of sunshine and 40 degrees vehicle interior temperature! Fortunately, not with iPhone!
Thus, only 2 stars because I now had to return the whole and must look for a new solution!
