Neutral: The background is smooth / shiny and attracts fingerprints magically.
Negatives: The mobile phone is indeed perfect in the shell, but the shell is too tight, so be operated by the shell itself, the buttons for camera and volume up / down. The camera button, although I can turn off because I do not use this button anyway, but the problem with the volume / bar - buttons is annoying. Example: I press quieter, the envelope pushes loud.
Without the negative points I would it 5 stars, but only so. 3
