The real Lifeproof case is actually made in China as well. The two almost look alike right down to the box and accessories / literature they come with. Remember when you purchase a fake case, it takes away from the development money the legit case manufacturer has. In this case (no pun intended) you also might have issues with the fake case not fitting perfectly.

There's a lot of money on the line here! You choose.
