I already have several mobile phones Blackberry, Samsung etc had. Especially with my S2 and S3, I often had the problem, cover the cases the user keys too. Not here. The shell is super flat and you can easily operate all function keys. The charging socket is freely accessible, so that no loose contact at connector occurs. The shell itself is semi-transparent. This allows you to continue to recognize the actual Iphone color and logo. For me the Iphone black and the shell is green. Adjusts color very well. I've bought the cover for an iPhone 4S. No wobble or fall out of the envelope as in many other manufacturers. In addition there is a protective cover for the front that fits exactly. No cutting required. And a little cloth, so you apply the screen from the shell of debris and can eliminate otherwise. Those who want to protect their iPhone so effectively from scratches is super advised with this case.
