The description of the item could be better, as it's not a case a such, its basically a screen protector. I can't tell if its a genuine product or not as it fitted ok, but not perfect. The item is actually a replacement phone back and a cover that flops over the screen, but doesn't flop enough so it sits on screen, but that may change over time with use.
The reason I wanted a case was to stop me switching phone on while it was in my pocket, and this screen protector didn't help at all.
I ended up buying a leather flip series case cover for much much cheaper that does the job i wanted.
