The first thing many people do when they get their iPhone 5 is try and protect it from getting damaged by adding a screen protector. The most recent screen protectors for the most part are made of glass. In this comparison I test the Spidgen Glas.t slim, Bodyguardz Pure, USG Impossible, and Armorz Stealth Extreme R. I tell you about my experience with each and then at the end, I scratch test them using keys, a screw and a knife. 

Check out the video to see which one(s) hold up best.
