I should preface this by saying it's the nicest screen protector I've ever used. It's crystal clear and has been great since I picked up the phone. I'd like to see what else they have, but t-mobile just rebrands it as their own. My daily driver(Galaxy nexus) should really have a screen protector on it, but all of the ones I've tried make the screen look like crap.
It really is surprisingly good, if you don't have a screen protector yet, I highly recommend giving this one a chance.
