Its a original Samsung hard plastic case that i bought for 30 euro's, it looks ok and seems to protect the edge pretty well for just a back case.
But the problem i have is that every time i end a phone call and take the phone away from my ear 1 or more hairs from my beard get stuck between the phone and the case, and that hurts.
So if you don't have a beard go on and buy it, but if you do have one you might get hurt.
