Super Case for Z2

I have originally bought this envelope, on the one hand to protect my cell phone and on the other hand according to the optics but maintain largely.
A silicone case came for me due to the lack of surge protection is not in question.

Positive
+ No loss of Sony optics
+ The bumper protects the frame of the phone properly (falling from 1.70 m on asphalt kratzerlos)
+ The transparent back cover protects from scratches
+ Lightweight protrusion of the bumper on the front protects the screen
+ Helps spite of protection to only slightly

Negative
-The Bridge over SIM and Micro-USB slot is slightly loose (If after prolonged use no longer, however, has bothered me in the first time.)
-Can Depending on the activities and loads discolor slightly

After the sheath about 3.5 months heat, soot, dust and slag oil was subjected to daily, she was stained rather yellowish. However, I was happy enough to buy me the same envelope again. I can recommend it only.
