Hi all, Searched around fr an answer but to no avail. Which is better for scratch prevention? I've seen Zagg videos of some pretty hardcore key action against the Invisible shield but it's always turned out fine. Is this the same with the Power support films? I've heard they are better than the Invisible shield in terms of clearness and now of that yellow tinge issue, plus I personally like the seperaye cut for the front camera and ear piece rather than one big hole which the Invisible shield has. Thanks guys P.S - Where is the power support available in the Uk?
