Let's be clear: it is essential to protect smartphone against a minimum the risk of scratches and even more shocks and drops. This case replaces the original back with a flap for the screen. For the flap really take its place, you should make a habit for ten days regularly ask your device side flap table ... if you see him constantly "yawn" and will be interviewed about its usefulness. That said it is the "least bad" of such product found. We especially regret the lack of a flap of the locking device, a simple scratch would just ... more, and this claim is unfortunately common to all cases of trade, attachable wrist strap to the "hard" of the canister would be highly desirable. Anyway, a few tweaks and you can adjust yourself :-)
