There is very little difference between quality glass screen protectors. It is how they are installed that makes a huge difference. The only one I have used for my last 2 iPhones is the Spigen Tempered Glass Screen Protector. What makes this one the very best is the installation jig that comes with it. It positions the screen protector correctly every time.
The secret of a good install is getting the screen totally clean, and make sure there are no cats with in a 20 square mile area

. Get a bottle of 99% Medical grade alcohol. On your desktop place a damp kitchen towel place the iPhone on this, this will ground off any static charging, plus the dampness in the air will stop any dust and hair. The wimpy alcohol pads supplied just don't hack it. Putting on talcum free rubber examination gloves first with a cotton pad soaked with the Med grade alcohol scrub off the screen. let evaporate and scrub it again. This time I dry the screen with a dry cotton pad. Next I polish the screen with a new out of the package microfiber cloth. finally I blow off the screen with a watchmakers dust blower. Now I can install the screen protector.
This Rules!!!!!!!
