The shell is made of grade material, and the base is well made and aüßerst practical. The fact that the rubber part of the case covering all edges and even protruding slightly above the edge of the display, the Lumia is perfectly protected against falls.
Mir is the mobile phone in the envelope even dropped the one time or another, without make it obvious. Upon impact on the ground, the mobile bumpt aside and then (the display but does not touch because of the protruding rubber edge with the ground) lands comparatively gently on the back or display.
Even the back is flush with the camera I find great, is easy on the paint the camera.
The side buttons are also well protected and can despite envelope properly operate.
1 star, I still have to deduct, since the shell is not very nice and the Lumia makes pretty clunky, making it sometimes a little hard to get out of his pants pocket. In addition, the cut-outs for headphones and charging cable are a bit small. For my Shure SE-215 I have the envelope each time and decrease slightly thicker charging cable could pose problems.
Also, the "tightening" of the shell is a little fiddly and requires sensitivity a little. I would recommend the phone to first place in the rubber cover and then the side of the control keys advance obliquely introduce into the hardcase. The side without control Tastetn can then simply push down and finished.
A strong buy recommendation for all, where the security of their mobile phones more at heart than the optics!
