My thoughts...DO IT I have owned many devices and have gotten better putting screen protectors on. They have saves many devices. I am careful with my devices, but they get thrown in bags on car seats which they may slide off etc. Despite what others say I have had 3 iphones and many ipod touches. Those with a zagg have perfect screens those with out have micro swirls that are etched in the screen and make it more difficult to view. IMO they are worth the small price. The key to apply - work in a dust free area, use a new lint free cloth to clean the screen, wash your hands or better yet wear nitrile gloves like found in your doctors office and follow the instructions. Don't rush good things take time.
