Only surprises me a little that at the bottom of the holder is a small bar that you should fix the floor with double sided tape. However, contact with the ground is not because this is not the lowest point. To establish the contact, the foot would (large visible rear plate) between the base plate and the front face (the car, here silver at Warnblincker (see picture)). Only the gap created would stretch to the entire area, which I did not want. But it's also no gap between the two parts of the car, even if it probably not quite the Dinne the inventor is.
Anyway, I would bring me back!
