The positive first: The support really budge on the disc. Simply ansetzten, flip the lever and you're done. You do not even need a lot of pressure or the suction cup has to moisten as in many other manufacturers. The mobile phone can be inserting easy, thanks to the variable side brackets. The "tail" can be completely removed if you want to, but is not absolutely necessary as an opening for the charging cable is available.
Now the negatives: The holder vibrates tremendously while driving. As today's mobile phones all reflect how stupid you always twitching and thus annoying reflections in view. These are, depending on the time of day and direction of travel sometimes more, sometimes less, but always present. That may be different depending on the vehicle!
Next rattles the part when no phone is used. Even at lower bumps in the road, not only on cobblestones. This can be remedied by (where the mobile phone used) the head of the holder decreases. Thus the problem is solved, but now you have another piece of what you put in the glove compartment or center console, and must accordingly came out again.
And as if that were not enough, the spherical head keeps the weight of the phone is not sufficient (although the Lumia 630 with 134g weight is within the specifications of the holder). Once it becomes uneven cut it in the head. Not abruptly, but always a little bit more so that you, depending on the road, every few hundred meters have to readjust the part. Cobblestone streets you should completely avoid. Very annoying! A connected charger (new and spiral cable is not worn) pulls the thing down immediately. Even in the state.
All in all, I am rather disappointed. The very good impression is conveyed to unpack the bracket after made very quickly destroy the car. If one finds one is not just absolutely ideal road conditions more engaged in the bracket as a drive by car.
