The shell itself is rigid, surrounded by a gray stripe harder, the set provides very good protection. In addition, the standby button (or end of standby), volume protected by the shell at these locations with protection "molded" adapted.
The "do not disturb" button, the USB connectors, transistor and headphones are also very well protected is always accessible (safety plays on depth).
But innovation that makes it a really interesting case is the use of flash to alert you to calls, notifications on different modes, ideal in noisy places (such as the presentation signal), or otherwise silent or even meeting . The set had its effect which adds to the aesthetic value rather ingenious.
Finally: a resistant shell that stands out from the competition by using the flash mode very useful in certain circumstances. The price compared to the quality of the product is really fun.
For the occasion, I decided to leave aside my old protection to adopt it, more aesthetic and useful.
Very Satisfied.
