You guys that keep looking for the holy grail of screen protectors, that cover "the whole screen" are going to be very disappointed, and/or pay a lot of money for very little.
The curved body of the iPhone 6/6+ make this near impossible, or, at the very least, cost a lot of money to do so.
But WHY do you really need this type of coverage?
What is the real risk of having a very, very small gap between the screen protector and a good case that wraps around the iPhone and provides an edge/lip on the front???
I think there are many good combinations of case and film screen protectors that will serve you well.
My personal choice, which has been working very well now for a month, is:
I'm sure there are other combinations that may work as well. But, IMO, looking for a screen protector that covers 100% of the screen, including curved edges, is a futile effort.
Good luck to you all!
