I got a pack of the Zeiss Pure Crystal screen protectors.
It's not bad. easy to put on. no bubbles. Leaves about 2mm from the edge uncovered. This is good with cases.
very clear but not as smooth as other hard protectors i've tried.
It does leave finger smudges, but doesn't affect the display quality. You'll only notice the smudges when the screen is off.
So far it's a keeper. Until I see better tempered glass protectors out there...
