This is my third case for S4's - And finally A, when there is nothing to complain about. Except maybe the slight IPhone 4 optics ... The back feels very smooth and sits comfortably in the hand. The smartphone will grip and not much thicker. Now it must put away good only possible falls.
Addendum 08.05.2013:
Mir is the mobile phone fallen far twice from the hip to the ground and every time the S4 has jumped on a corner of the envelope. So unfortunately, the case protects not optimal because it is not secure enough. -1 Star
