I bought the original Nokia Lumia 820 Holder for my because I wanted to have a stable, high-quality, visually discreet bracket. The Lumia 820 also fits perfectly into the mount, the right cheek picks up right between Entsperr- and camera button. The service works perfectly. To charge the smartphone even has a small cutout in the lower jaw is available for a charge cable so that the Micro-USB port remains free. Visually, the mount is very discreet and well-made, as I expected. The neck is a little longer than it acts on the product image. The loosening of the mobile phone from the holder works with a small button on the back of the mounting head. When the phone is taken up in the hand when getting out of the car, you can operate with the little finger, the release, which works very fast and intuitive.
On the negative side to assess that when no Smartphone is clamped the holder rattles. That really bothers me, because I do not equal the mobile insets for short distances in the holder.
