Invisisheild is by far the best screen protector out there. It completely stops the smudging you get when your hands aren't the cleanest. it protects the screen from random things scratching it while it's in your pocket. and compared to any other screen protector it goes on with ease. so easy they let the minimum wagers at best buy do it for you. the only thing i've ever found to be a problem was my first droid **** the bed and i needed a new one. when i peeled off the sheild it was stained from oils on my hand over the last seven months. now i didn't notice the stain while it was on, just after i took it off. So thanks to an awesome lifetime warranty, i called zagg, and they sent me my new one. no other company does that.
