The lower brackets have no lock on the side, and thus the first bracket is eventually disappeared during the second or third fall out in the car. The same also applies if you blindly working on the screws, since no backup is simply present and eventually it is out a little mother and disappeared into an unreachable or not searchable niche ...
Otherwise, the part makes stable, which it should. The pivotability is limited, but this is planned and simply designed for smartphones in portrait mode. Enigmatic remains for me, why the manufacturer did not use more care on the weak points. Who needs to change cars more often, should look for something more durable.
