Product's quality is best you can get.  I never bought one of these protector films before so i was clueless.  Its a little tricky to get it on at first, but u can keep peeling it off and retrying without a problem. Make sure you are working in lint-free area because thats the only trouble you might have.  It can also works with my new completely covered ivyskin case. Recommend to anyone in a heart beat! just buy it its cheap with the greatest quality.  No brainer!
