Original Review:
The suction cup holds a privileged location on disk. The Z1 is firmly seated in the tray. Unfortunately, due to the rather tight lock is not possible with one hand take. Except maybe for experienced pickpockets ...
No wobbling in poor road and no engine vibration affect the image quality.
A knurled nut behind the joint makes it possible to loosen the head and to adjust so. But you already requires quite a lot of strength for it.
