I took it and put it on a iPhone 5S. The case follows the contours of the phone. The fineness is we do not feel any difference to the handling or in the pocket. The shell is flexible enough to be easily installed, and rigid enough to hold well. It does not amortize the falls but very well protects edges and back against small bumps and scratches. The protective film of screen comes with is very easy to implement and provided small towel cleans well. The film is invisible when in place.
