Convenient but seems shaky

Pack well equipped (mini cloth, screen protector, stylus eraser, strap, hull). The shell-casing has a notch for inserting a card or some business cards but I think it will tear rather quickly since no thick.
The whole is good-but the case is too steep and I think that with daily use, it will not last long at the crease, to see ....
The style has gum eraser tip a little too round / too thick, suddenly it's not so easy to press a touch key especially on the claver Samsung S4 ...
For the price, he will make his office for a year I hope.
