Silicone Case fits well, does not smell of plastic protects the Z3 us well so far against scratches. Since I use the magnets for charging, I was quite happy that the recesses of the envelope on the right side were, in other words those who want to invite his Z3 via USB is wrong with the shell. What has been a bit strange at first that the buttons are covered for volume and for the camera (however described and seen) Yet everything works as it should. Furthermore, the casing has a corrugated surface at the sides, so you can easily pick up the phone off the table, without fear that it slips from your fingers. The back is "non-free" strong buy recommendation.
