I have this shell for a while now in use. Herein, the phone is well protected. But it is a shame that the view is still significantly worse than without the "wheel" on the day. This looks superimposed as many protectors. But particularly evil is telephoning. Due to the broad scope there is only a narrow channel for the sound to Mikdro and thereby it has a distinct Richtcharekteristik. The phone partner understands a not so good, or only a low.
One should be aware that the shell phone but significantly enlarged.
