fulfills its protective function is sometimes something impractical

The shell is quite well adapted to the Iphone. Holes for charger, headphones and camera are available. There are also increases in the shell, for example, to indicate the location of the on-off switch or a volume control. About the design is debatable. The shell covered up on the screen and the home button so far everything and so can be seen from pretty much not Iphone.
The protection function in combination with a display sheet is given. However, what is very bother me personally, that the phone when it is in the rubber sheath, can do only very laboriously in a trouser pocket. The non-slip rubber makes it every time again a game of skill.
