The housing is made of hard plastic with a rubberized inner core. The mobile phone can be used easily and stops reliably in the shell. The front edge is also rubberized and is approximately 1.5 mm forward off the screen, so this can be reliably protected.
The black rubber strip on the outside are also minimally elevated and prevent a slide around the phone. Recesses are provided for all the openings of the mobile phone. Even the infrared transmitter is not obstructed. Even somewhat larger than the charging plug Samsung Original can be plugged easily.
The side buttons on the smart phones are also protected under a rubber coating. These key covers give the pressure point of the keys to continue well. They require a slightly higher compression force than without protective cover, for they are but as far as sublime that the keys can be pressed better than without a mobile phone.
The only downer is the opening for the mini-jack headphone - this could be a bit bigger. It is sufficient for most conventional in-ears, but with a diameter greater than about 6 mm for the handle of the plug can no longer insert this.
