First of all I must say that the shell is processed dibasic. The leather is resistant, inside with a kind of felt material disguised to protect the display. The shell in which the phone is sitting is very robust so that's almost difficult to get the phone back out if it sits there again. But everything goes once you get the trick. The magnetic closure keeps perfectly.
Now to the two weak points. It would be nice to work on the phone when the flap would work way up as an out. She's been so many times in the way. Thus, the are no recesses in the lower part of the flap can charge your cell phone only when open the envelope.
