The case is processed good in and of itself and looks from the outside with the leather quite good, but it's a pity to hide the elegant Metalic look of the HTC One. The power button, the headphone jack, the charger / USB port and the camera are all so that they are recessed within easy reach. By the magnet on the flap, the case you close almost automatically, as soon as it flips. The smartphone is fully functional in the case. I also have the impression that the smartphone would survive easily in case of a fall from moderate height. However, it bears in Case already on much thicker. Is from the 50mm thin phone a 1.7-1.8 cm wide case, also in the length is about 1cm draufgeschlagen. A bit annoying is that the cell phone so stuck in the Case that it's a small effort to pfriemeln it from the inner plastic frame.
