NuShield touts the fact that it supplies the military with its DayVue anti-reflective screen films. This is a thin film that was designed for the original iPad but works with the iPad 2 and third-generation iPad. I was impressed by how easily it installed without any bubbles. As advertised, it also helps with outdoor viewing, though you will get some glare when you tilt your iPad at certain angles.
This is a "dry" installation and what's nice about the NuShield DayVue is that once installed, you really can't tell you have a screen protector on your screen.
Note: The film covers the iPad 2 and iPad 3's front camera. However, it doesn't seem to impact image quality (the iPad 3's front camera is not nearly as good as the back camera). The film does impact the clarity of the new iPad's Retina display.
