Got my Tech Armor Ballistic glass a week ago and thoroughly love it. It has the U shaped home button cutout and a tiny cutout at the top edge for the camera. Like all protectors it covers only the visible screen area. But this is not a flaw, just a characteristic common to iPhone 6 and 6 Plus screen protectors. It was the most ridiculously easy install I have ever done. I used the hinge method and it basically installed itself once I placed it down on the glass. It's very resilient to fingerprints and the few that appear wipe away easily. Compared to plastic PET screen protectors it stays so much cleaner. I'm highly satisfied with this product regardless of the cost. When you factor in that it was only $9.31 it's a terrific value too. In fact it's better than the one my friend had installed at an AT&T store. That cost him about $40 and he was so dissatisfied with it he tore it off a week later.
