She looks pretty good overall, but it has in my estimation, a capital planning errors:
There is simply no appreciable shutter.
As a result of the somewhat lapprige lid simply comes up when gravity wants it. To lay phone so in a bag or suitcase is not advisable, the lid is open, the display is no longer protected and therefore is the meaning missed.
It should be noted that even the display automatically activated every time you open the lid. This option like it is not really due to the above-mentioned unplanned openings.
Recommended it would probably be for people in which the mobile phone always demurely sitting in the jacket where the lid can not just open. As has already been said: Visually, on the sleeve not be faulted.
Conclusion: Not for me - I'll take back my sock!
