Thanks!
So I got the screen mate flex. Definitely everything it lives up to be. At a glance after installation, the phone looks naked, and feels naked too after a few hours of use (the screen gets smoother as the rough coating wears off, as per mentioned in the manual). I am a huge fan, as the surface of the protector feels just like the bare glass, and is thin enough to be near invisible and have minimal interference on that original touch ID feel.
The only caveats I have with it is the edges - I really enjoy the swipe from the left feature to go back in iOS 7, and sometimes my thumb catches the edge of the protector. No big deal, though, as I have learned how to avoid it and still have a smooth swipe.
Installation was a breeze - just follow the instructions, only took 5 minutes. WORD OF CAUTION!!-- Get it right the first time. Clean the screen and make sure nothing is going to land on it (dust). I began placing the adhesive side on the screen and noticed it was ever-so-slightly mis-aligned, so I pulled it up again to re-align (mistake). I ended up with a tiny spec under the corner of the glass and, although nobody else could notice it as i was showing it off, I knew it was there. The protector is so clear that it looks as if the spec is on the surface, not underneath. Moral of story: Get it right the first time.
Other than that, amazing customer service, and a really great product IMHO. The only one I would put on a new iPhone.
