The front cover is very thin, but quite stable and the rear replaces the original rear panel (battery cover). This leaves the "total package" of phone and shell very light and thin. Thus, this design results in a barely brushing neat and solid protection for the screen against scratches. But even for this !! only The fact that the front cover easily pops up and the phone is not enclosed, there is no protection for the casing, for. Example, if dropped. If it comes up very unhappy and / or pops up in the traps of the lid, and the display may break.
On the other hand, because of the openness of (me well pleasing) metal frame of the mobile phone continues almost entirely visible (except for the hinge-side of the envelope). To be fair, it must be said that all this can be seen from the pictures and item description and was aware when ordering.
