That's typical wear on smooth TPU. If you want something more durable get a Magpul case. At least the case did its job, your phone should look pristine![]()
It's actually not from my experience. My Belkin Grip Candy (the non-translucent one) has a black TPU back, and it's in pristine condition from what I can remember, and I used that thing for more than twice as long as my Neo Hybrid.
I have a Magpul, and I love it! I use it when I want a change every now and then.
