I have been a long time user of the $10 3 pack of plastic film protectors you can get on amazon, they work fine however after a few months they get scratched, hold tons of fingerprints and need to be replaced. What I'm wondering is would a tempered glass screen protector necessarily have any better fingerprint resistance or scratch resistance vs the plastic or is the only real advantage the fact the the tempered glass will shatter if dropped and not your phones screen. I'm considering the zagg glass only because of the free replacement. I previously used their invisible shield on a nexus 7 and was not impressed at all but am willing to give them another try only because of the free replacement.
