How tough is it in comparison to it's other competitors. I've heard it's prone to showing scratches. Also, how does it compare to the Anti-glare version in regards to scratch resistance. In comparison to my EDGE iPhone with the original Crystal Film, it seems a lot more scratch prone. I've had mine for less than a week and there's already a noticeable scratch on it. The old Cystal Film on my EDGE iPhone looked MINT even after a year in the same exact day-to-day situations.
