I have seen many car tried holding devices for smart phones or navigation devices. The car holder from Samsung is perfectly finished. Nothing is loose or vibriert.Der insulating foam is very high. The clamping device has a very fine teeth and is slightly bent at an angle so that the device which is clamped to the front not falling kann.Sitz absolutely fixed. I can only recommend the Car Mount. It fit so well into how all phones Navis and smartphones. So buy!
