Within two days of the appointment of the universal bracket supplied. The holder is held in a very noble design and still looks robust. The jaws can be opened by gently pressing down and the Lumia fits in, even with a protective sheath. But first, the bottom pad has to be something to match the length of the Lumia 920, so that the jaws are exactly between Kameraauslöse- and on / off switch. Through courageous squeezing the jaws sits the Lumia 920 bombproof in the holder. Since the lower bracket has an opening can be plugged a charging cable to the phone; which is unfortunately a bit fiddly until the connector is firmly seated. The suction cup is very easy to attach to the windscreen of the car. The integrated Helbel in the arm of the suction cup ensures a secure hold on the disk when it is closed. Now can the Lumia 920 to the holder easily stuck to the arm. A test ride showed that even on cobblestones or rattles nothing wobbles. The arm might be 2-3cm longer, then an operation of Navi could perform more pleasant than the driver. He might be too short for people with short arms. My first impression is overwhelmingly positive and can only recommend the Nokia CR-123 Universal Holder incl. Suction base for the Lumia 920.
