I've used it on my Curve, but it only lasted about 2 months. It began to peel off and look awful. Zagg does have a warranty that will replace it, but I didn't feel like using this on my phone again. I'm going to try something else.

I have had invisible shield on my bold for 6 months. No peels and still protecting. You should be aware that there is a slight orange peel effect that people in this forum complain about. If you expect the surface of the screen to be as smooth as glass , it may not be for you.
