I have four children, so I always put protective glass on my devices. I've had several different brands but this one was the easiest to install. There were two components that I have not seen in other brands. First was the alignment sticker mentioned in other reviews. They may seem a little cheesy, but they really helped. The second was a round sticker to collect dust from the screen. A bit funny, but actually useful. The last difference I liked is that the "card" you use to press the screen and remove bubbles has a felt cover at the end. Not sure if this is different in function, but I've never liked the "credit card" style used by other brands.
