When changing the phone regularly, it is nice not to have to change all the accessories at the same time, thanks to this support, this is the case. It adapts to the smallest m (otorola Defy) to largest (samsung galaxy note 3) through the traditional gps tomtom or other object.
A 7 "tablet in portrait direction yours also.
It is perfectly adjustable and few be placed anywhere inside the vehicle.
I highly recommend!
