I do not trust the suction cup to my phone.

To my mind, the Lumia 920 is much too heavy for the suction cup. I do not want to imagine me, if the phone falls with the advancing down display on the center console with shifter and handbrake.

The part that the phone itself is holding, however, very well done:

+ Phone budge it.
+ Nevertheless, it can be used with one hand and remove.
+ The speakers are free, as are the control buttons.

I simply disconnected the phone holder from the suction cup (is quite simple, just plugged in) and this put on my existing Amaturenbretthalters, in which I could just as easily remove the cradle of my old phones.
