The bag fits well around the phone and should be able to protect it reliably. The side buttons (on / off, volume-Quiet, triggers) are, however, completely covered by relatively thick plastic casing and can be operated only with difficulty; a pressure point no longer can feel and the key operation is sometimes a matter of luck. The valves for micro-SD and SIM are fully covered, should the product for an exchange of the envelope.
The cutout for the camera and the LED are very deep and quite narrow so that when using the auxiliary light a lot of light is scattered directly into the camera. The images are then covered with a light veil and hardly usable.
The bonding of Kunstoffhülle with the leather jacket is mau at the corners, because the corners come off during transport in a pocket and stand tall. I will probably fix with a dab of superglue.
