This purchase I could really save me. Here one must unfortunately stick from the car, the base plate with adhesive bottom on the dashboard. Then you will not gotten the base. What then the car rental abroad? Buy even a holder! I should have sent back the nonsense. Here I got from foreign manufacturers over Amazon a better holder for only 10.-. This can then also attach to the windscreen with the camera of Sony. I am indeed on Sony products, but here probably someone was missing the imagination in the car work with want to.
