I ordered this envelope, because it is so cheap and actually have expected nothing good. I expected that the material feels cheap and the transition from transparent to colored border is poorly processed. But I'm super surprised, the shell is far more beautiful than the one I had previously purchased in an electronics market for 10 euros. The back is really absolutely clear and not milky, which looks very nice, the transition to color (in my pink) is not felt. All connections and sensors are free, only the bottom right is with me a recess in the form of two small holes, which is unnecessary, but not too disruptive. Particularly positive: Up at the port for the Klink- plug is a small flap that closes it and so protects against dust and water. Disadvantage: the beautiful, clear but consequently very smooth backside is this 1 fingerprints slightly dirty and 2nd is the Cell less grip when you hold it longer in their hands, the surface is sweaty. In my opinion, the envelope is really great, both functionally and visually. I can only recommend!
