COMBAT(TM) Apple iPod Touch 4th Generation 4G Premium Screen Protector Shield with Lifetime Replacement Warranty - Retail Packaging
These are my favorite screen protectors I've found. I'm a college student so my ipod is constantly getting thrown in backpacks, purses, etc and screens scratch very easily. So far this one is holding up well. Mostly though I was able to put it on with just one little bubble in the corner and it doesn't feel intrusive. It is nice and clear and slick so it doesn't take away from the quality of the screen. I'll buy again.
