only as good as the car where it is mounted

In this combination, the holder works very well. The mobile phone can be supported on the dashboard, so it has a very good and stable support in both portrait or landscape format. Even when using the cell phones it does not wobble.
The one-handed clamp the cell phones will also work well. Although the take out is also single-handedly, but the Airframe then something comes out of the ventilation grille out and has to be pushed back by a short press.

A friend of mine has the AF2 + briefly tried in his Audi A3 - there it did not work. In the round ventilation grille a cell phone could not be fixed without wobbling.
