But for the shell is super convenient. And at this price can not complain. I myself just for that instance (in red) decided because unlike some other cases, can be placed both horizontally and vertically. Other cases (with a few exceptions) to leave :( only the horizontal positioning
And "limp" is the envelope with proper installation and proper no longer fold: D
In addition, like the shell "clunky" appear .... but even folded it is still thinner than a typical paperback.
So all in all: a recommended product!
