My experiences I have gained in the meantime, I will now give in writing to do so.
I can anyone who thinks twice about whether this support really stuck just say that the suction cup (self-adhesive + vacuum) enters into an incredibly strong connection with the body panel or the vehicle windows.
Mounted With 200 km / h outside of the vehicle I had no problems with my test drive.
Who wants to know what a force attached to this mount the camera on the vehicle can be happy even try to sucker + camera sucked state to solve.
If you are still not completely convinced, you can try the experiment with unlocked suction cup.
Here you will notice that the suction cup itself without suction withstand extremely much force as he himself sticks (I think it is here a special surface in the game, which works like a gecko's foot).
The camera can be tilted on the bracket by 2 axes and also rotated on the mounting plate. You can easily move any angle on the vehicle in the Focus.
Whether inside or outside - the camera will not budge and budge a single millimeter.
From me there is a strong buy recommendation.
