The protector is easy to install. Took 3 times but only because the screen is so big there is always a little dust creature wading past to create a bubble. Once removed, the protector simply sticks to it and is fun to watch as it works its magic. We've only had it a day so I can't comment on anything other than the app, but I definitely feel better letting our 10-year-old daughter use it for all kinds of educational apps and of course phone calls.
