So I have purchased four Otterbox Defender series cases, but I have always had the same problem. After a while of use (I use the case all day everyday), the built- in screen protector begin to scratch VERY easily. I know many other people have these problems too. I realize that there's not much Otterbox can do to fix this because I've never seen a screen protector that doesn't scratch. However if you don't like scratches, I recommend the commuter series, which enables you to change out the screen protector, whereas with the defender you can't easily remove it.
