This protective cover is good and solid processed and thus has no chemical smell or the like. The surface itself feels very smooth and flat to which she is also slipping. The mobile phone could be easily inserted into the envelope, sitting there very well and makes the phone thicker minimal. Very good, I find that the shell can withstand some of the display. If the phone now with the display facing down on a pad, is not display on the pad on, but has the supernatant of the protective sleeve as a buffer. My cell phone is unfortunately already been dropped a few times - luckily the shell around the phone. I assume that the phone would have taken a loss in the normal case, as it often falls on the corners. Fortunately, the shell has the shock absorbed well, so that no damage recognizable still be felt. Strong buy recommendation for this envelope.
