Satisfied, used on Polo 9N with Galaxy S4. The support remains discreet, and you can easily install the phone without having to use 2 hands, and without too much hassle, while driving (I know, should certainly think of putting before you start driving ...). The smart cover (official protection Samsung) goes smoothly, returned behind the phone. I used to landscape mode, not that it does not hold in portrait mode, but I am always afraid that if it falls too bumpy road.
The "clip" forming a kind of cross, it can climb vertical as horizontal blades. Furthermore, once installed, can be rotated all on itself, a notch every eighth of a turn.
Attention the slope is not adjustable, consider watching closely the position of your air vents. The fastening system is simply a kind of pliers, we just slip on one of the blades of the ventilation system.
