This product is a little expensive, but it is glass and does not scratch, at least not as much or as fast as a film "plastic". And what a comfort to install! Since protection is rigid, it is placed alone. If a bubble gets stuck, it raises and presto! We hunt the ugly bubulle, it's over, and that does not move. For now, after falling 2-3, it did not break. The cut is perfect for Galaxy S IV. It cleans very well with liquid glass cleaner. Do not alter any of the brightness of the screen. So I prefer to put more money and have the benefit of all these qualities!
