This product is described as a "glass" screen protector but I doubt it's real glass. It's more flexible than plastic. However, on my Zenbook Pro Duo, it's a crystal clear image. This is about as good as it gets in terms of the main screen setup. Installation was incredibly easy. There were 3 blisters in total. 2 of these resolved themselves within seconds and the third took me less than a minute to get rid of.
