Screen protector for what? To protect against your sharp beard?
The screen is GLASS. Screen protectors are a waste of money. I've owned every iPhone since 2007 and I've never had even the slightest scratch on any screen. And that includes one iPhone that I dropped on asphalt.

you must be very lucky. Original iPhone less than a week in, it was ALWAYS in my pocket or hand thats it. big ass scratch. I got it replaced but i have been screen protecting ever since. I don't trust their claims.
