I have used the rhino shield on two phones over the last two years, a nexus 4 and nexus 6. I have dropped my phone a thousand times at least from falling out of my pocket while riding my bike to getting stepped on while charging next to my bed. In all that time the rhino shield has protected my glass screens and they look brand new when the shield is peeled off. The only negative thing about the rhino shield is the edges aren't perfectly flat to the phone screen which can cause it to snag and get worse if a phone case isn't used. It could be due to user error when installing it in the first place. Don't hesitate to purchase this product, it will save you from having to replace broken glass, screens, and lcds.
