I had one on for a few weeks. Then I realized how stupid it was. I'm have a leather folder type case so when not in use its always closed, so screen is not exposed always like a phone. I am the only person who ever touches my screen. 5 month later screen Still is perfect. Only way it could get scratches on it is if I am stupid enough to close leather case with rocks in it, (or sand). lol
