All in all a very robust part. Very stable arm, large-sized suction cup with good mechanics. The position can be adjusted well by the buttons in the joints. However, as is also a small flaw. When the button for left / right adjustment I find the stops between the individual positions too far, which is why the holder at a set position at the end of the front but can jiggle a few millimeters to the right and left. One can move from stop to stop back and forth, so to speak him. During the trip, however, I noticed nothing of it. So I think that I can live quite well.
