Well for the Interview we asked permission to throw a water bottle at the screen as a demo. Well water bottle #1 really did not hit very hard. Andy decided that was not a good enough test watch as water bottle #2 really whack the heck out of the screen nearly knocking the TV over!
Needless to say it worked as advertised protecting the screen and beyond about giving me a heart attack I am convinced that you would be well invested to protect your LCD screen with TV Armor.
