Commercial side nothing wrong, I received the package on time, well packaged, fully consistent with the description, the fit is absolutely perfect, no game, and little extra that is not specified and which should, c is that on the inner surface levels knobs and corners of the iPhone, there are foam to prevent scratching !! The catch? It's a matter of perspective, but the hull created an over-thickness on the contour of the back (laid flat, the hull is slightly thicker than the iPhone, and once installed, the front is flush with the hull, but not the back). And if the outside of the hull is rounded and pleasant to the touch, this is not the case angles that are on the surface and to the inside of the shell, suddenly the sharp edge of sensation on the fingers that are So as the iPhone, is not necessarily pleasant. But for that price, hard to beat, and then you lose in comfort is safety in addition to the back of the iPhone ... On flat surfaces anyway. Anyway, I'm happy with my purchase !!
