I got a speck candyshell today for my iPhone 4s and needed a screen protector. The guy at AT&T strongly suggested the Moshi screen protector so I got it and he put it on for me. I know the price is kind of high so my question is, is it really worth it? I hope to never have to replace it again, but not sure how good they are at holding up. Anyone else using one? If so does it hold up pretty well? Thanks
