I was installing a Zagg Invisible shield onto my friend's iPad and it immediately had scratches once I put it on. I'd hate to think that I scratched it, mainly because it is scratch proof. Also, I don't know how I would have scratched it being that the only thing that touched the screen was the provided microfiber cloth (I was using it to cover the squuegee). Also, I don't think I ever Squuegeed out the water in that direction. Is it possible the screen protector came faulty?
