The only drawback in my opinion, however, the holder of the windscreen that starts to wiggle wildly at the slightest bump in the road because of the long arm. Here it is advantageous that the bracket is easily covered with a soft "fabric" that protects the iPhone from scratches etc.
The bracket supplied for the ventilation slits fits with my Golf 5 unfortunately very difficult and you have to worry that they can not be removed afterwards.
