I am very tempted to purchase this screen protector because I just got an iPhone 4s and I want to keep the screen, free of anything but here's my question, does it keep the retina display? Because it's so thick is there lower screen quality or a rainbow effect?
The retina display is indeed intact as there is no rainbow effect whatsoever. I can notice the thickness on my black 4S, but it seems to not be as noticeable on my wife's white 4S. I would assume that due to the white optical edges, it makes the screen disappear. Also the material that it is made of seems to resist scratches and fingerprint s more than the SGP Ultra Optics, and much better than the Ultra Crystal.
