Leather cases really very good materials seem to be robust. Only negative point in my view, the size of this case, it really is no cut just for S4, in my view a little small taste. The phone just fits into it, he even to unclip. It gives a whole a little stiff, the flap trouble happened at the back, so to load is necessarily closed case. I had a case of the same type and this brand for my S3, I had none of these disadvantages. But the quality is there, guarantee of longevity.
