Simple, but good protection against damage case

Protection: The cover protects the device fairly well against damage in (eventually inevitable) fall down. Although the display itself is free, it is the bead of the sleeve, which protrudes about 2-3 mm on the display surface at the edge, also very well protected.
The main camera of the rear window is only minimally lower than the surface of the protective case and is thus still somewhat susceptible to scratches, if the device is as usual placed at the rear side. I have approximately 1.5 mm thick lined the inside of the casing on either side of the camera aperture with small pads. Now the camera window is accordingly "deeper" and is better protected.

Functionality: fit and stability are very good. All connections and sensors are free and easily accessible. Also, the opening and closing the small lid for the charge socket is not a problem. The only functional limitation: The on / off button on the right side is very difficult to move through the envelope. It's annoying and could certainly improved by thinner material at this point due. Because of this and the aforementioned camera issues a star deduction.

But overall good protection for little money - buy recommendation.
