Hello, I have the Tech Armor iPad PRO (12.9") Ballistic Glass Screen Protector (NEW 2017). Although the company advertises it as anti-fingerprint, it is a fingerprint and dust magnet. It also smudges. In addition, although writing is fine, it is not butter smooth as I feel frictions when I move my finger across the screen during game playing. What is the best glass screen protector for the IPP 12.9" 2017? Is there one with excellent clarity but without the issues I mentioned?
