I ordered the ultimate shield one from Amazon, arrived today, very quick delivery. So far it feels good, need to fit it precisely as its just wide enough to cover the screen. I'll see how it holds up over the next few days, hoping it isn't as prone to cracks as the Orzly was.
I've installed the Tech Armor Ballistic Glass on my 6 plus... Pics on https://forums.macrumors.com/threads/1802756/
It covers the viewable screen area fully. Feels very smooth like the original screen and clarity is amazing. Overall happy with it, but this is my first glass protector so nothing to compare with.
