The sleeve fits snug and carries on not much, so that the phone stays nice and flat. The buttons for louder and softer, and the on / off switch is easy to operate. Of course, all other openings such as charger, headset are accessible. Even on the IR transmitter has been thought. The feel of the mobile phone is better through the protective sheath around a lot. Desweitern I have no sharp edges found could interfere with the phone, for example. All in all a good protective cover. Buy recommendation!
