Positives:
+ Fits perfectly around the Z1 Compact
+ Protection to almost all cell phone around (see negatives)
+ Jack and loudspeaker
+ Easily operated from the Case-covered buttons (as embedded in the Case)
+ Handy frame (the phone itself is a bit too slippery to me betimes)
Neutral:
o SD slot, SIM slot and magnetic charging port hidden (specifically identified and MMN. quite useful)
o Eye for wrist-loop free
Negatives:
- Opening for Micro-USB is significant vulnerability, there can be the case for the screen towards deform very easily, because only a thin strip TPU is left. Therefore, a star deduction (as this affects a fall exactly on the top left corner, I do not want to try)
For those who do not permanently change your SIM card, replace the SD card or use the docking station, so I can make a recommendation.
