The envelope is in two parts and consists of a softer shell and the harder "skeleton". Both together results in an extremely strong combination and is also easy to remove when needed again.
Since SwitchEasy several different designs and colors holds, you can enter his phone a personal touch. For friends of Understatments this envelope my experience is to just right, because only a very few connect an iPhone with this design.
The fact that the back of the case is not flat, may be a disadvantage for others, I personally rate the increased grip due to the structure later.
For less than 20 EUR strong buy recommendation.
