After much thought, I compare and chose this product. That was the theory. The practice after unpacking was sobering: While the Xperia Z fits perfectly into the receiving tray, all controls are easy to reach, but the rest of the shell is somehow warped and bent, instead plan to be on the phone, the lid is at the corners of a half a centimeter high, which is not be corrected even by repeated re-bending. The folding is no pleasure, because the material in the "hinge" much too thick and forms a bead. This is exacerbated when the two card slots are populated. Although the manufacturer indicates that the better would over time, but even if the material would gradually more flexible, quasi fatigued, it has to go somewhere, ie the ugly Aufbeulen maintained with security. So back and not buy recommendation.
