As I said, the shell serves its purpose in your pocket. And I have not as yet left namely to protect the smartphone, fall. The flap can be easily fold back and the device is still well in hand and the shell is particularly easy. The only downside is that the flap when the device is with your back on the table, does not rule by himself and also has no locking mechanism. But if the thing is on the table, then anyway, because you want to look up. In a pinch, you can also just put the screen down. Nevertheless, a locking mechanism would not have been bad because so the "invisible window" is only effective. When you press the door on the screen. I have grown my own mount, with a bit of glue, a little Kustleder and two magnets does that quite well and did not even look bad. Perhaps "droning" the ever so from that in the end does so, but that I now did not want to hope.
