Unfortunately, there is one drawback. The side keys, both left and right are hard-very hard to press. Among other things, it happens that you regularly the volume buttons pressed in an attempt to unlock or lock the phone. The reason is that they are positioned on the opposite side and the applied force the phone pressed simultaneously to the left, where it is the other fingers at the level of the volume keys are with me. That makes it sometimes tremendously disturbing, the phone quickly turn on / off.
Unfortunately, this has not been thought through, because otherwise there is a high quality hard shell case.
