I have a 4400 mAh battery anchor with matching cover. Of course, because it fits not a common protection more. The shell is not just an eye, but it fits right on it and protects the back as well as the front - this is due to the overhanging edge that borders the phone.
Goes somewhat hard on it, but it keeps it right. And I have the phone both times in your pocket as well as in other bags. No slipping, no waiver.
One point deduction is really only due to the not so beautiful look. If there are other styles, then there is *****!
