Here's the story, briefly. Lost my iPod Nano. It was MIA for three weeks. Last week, I was looking for a dropped key in my son's car. Three weeks ago my wife gave me a ride to the train in that car and my Nano must have fallen out of my briefcase onto the floor/mud mat. For three weeks it was riding around on the mudmat, literally being stepped on with muddy, snowy, sandy footwear. I found it on the floor and was so depressed. It was a total mess. I figured nothing would work. Wrong! I gave it a quick wipe with a damp paper towel and it looks absolutely like new...and the click-wheel thingy also still works, which the Invisible Shield probably can't take full credit for. Anyway, I highly recommend them. I have them on the GPSes, camera LCDs, watches...anything like that that can be broken, scratched, etc. Measure the LCD - there is one that is the exact size on the IS website.
