After unpacking I could find a visually high-quality workmanship. Also the suction base makes a stable impression. The phone itself is Linkst and right of 2 brackets are fitted with foam inserts are held. to the lower part of the bracket are 2 little feet attached, which should stabilize the cell phone at the bottom.
Now for functionality: I am owner of a Samsung Galaxy S4 Active. A quite large, heavy smartphone. The two terminals right and left are quite spielig designed and unsuitable to hold such a heavy big smartphone. In normal road perhaps it may even go as soon as you like me but now and then sometimes paved roads leaves and moves off, the smartphone no longer holds in the holder.
In addition, the entire construction is a bit too "short or small." If one pinches the cell phone, it pushes up against the car window always, the angle is therefore not optimal.
My conclusion: Who has a small smart phone like iPhone, Galaxy S3 Mini, etc., is well advised with this mount. For larger smartphones you should pick out a different model.
