Very stable, it fit in well 4 cards and a few small notes or note the large open pocket, without the shell gets out of shape. Even after prolonged use, the shell still looks great. Property me the whole thing now, however, a couple of times down and dropped me is the upper part canceled by the edge, holding the phone. Nevertheless, the shell still works very well. When open, I have to watch out a bit, so that the phone does not fall out, but this is pretty good. Closed it's still super protected. But do not want to decommission the envelope, because it still looks very good and beautiful! Class part! To call the left ear should be used, then disturbs no "flap" in front of the face.
