The shell adapts and in black, I like the matte back even better than the glossy, fingerprint-friendly back of Z3 Compact. What I still like the fact that the covers that you no longer should always open, no cut-outs in the silicone shell are (SIM card slot). Unfortunately, that was not even made in the SD card and USB port cover so. Thus, the framework of the relevant 3 centimeters is so thin that it a little "lost form" the. This is of course due to the users who wish to charge the Z3 Compact via a USB cable. But I would avoid when using a silicone case as far as possible. The shell is so thick that the filigree cover the unit will survive the repeated opening not long in any case. Who buys a Z3 Compact, must also purchase a magnetic charger. Everything else is ready sooner or later problems. And then you can this "maintenance windows" in the Silicone Case omit what would make the perfect shell. But perhaps there is still time. As long as this is used just shell.
