For my application, these shields are perfect! I use an iPad in the cockpit and, without a shield, the reflective glare made it pretty unusable. With these shields (I also have a Nexus 7 in the airplane,) the glare is gone. The screen is much more readable, and probably a bit less sensitive to touch- which is good in my case, as bouncing around in turbulence makes a sensitive iPad screen overly reactive. See the YouTube video on how to install (by peeling only a small amount of the backing and aligning, then peel backing as the protector is incrementally laid in place. It takes less than a minute from cleaning the screen, to a perfect, bubble-free protector.
