I made a mistake using tempered glass. Yes, they are hard and scratch resistant; You can hit them with a metal object and they won't break, but the touchscreen underneath will break instead! You want a protector that absorbs and sacrifices itself rather than transferring impact to your device. These films are really good and have good instructions. They do not affect the HD quality in any way.
