I bought a 2 pack from ATT corporate store that is grease resistant. Helps tons at keeping face oils off screen, or at least 90% less than without. That's the only reason I use them. Being from ATT, the 2pack was a little pricy, but since I'm still on the first one from November 2011, $12 was doable.
