Apple iPhone 4/4s ScreenGuardz Pure® Premium Glass Screen Protector
Product Review (submitted on April 22, 2013):
These screen protectors are incredible. I purchased several for work and put one to the test with a hammer on an iPhone 4. I hit the center of the screen repeatedly, and pretty hard--much harder than ANY phone drop could cause. I eventually cracked the BodyGuardz, yet it still left the iPhone screen in perfect condition. I will definitely be buying these. Anyone who has an iPhone should have one of these on it!
