Although this display protection is significantly more expensive than others, I had put it to me. What good is a waterproof and dustproof cell phone when similar case of a fall the display is destroyed. The "stick" to the phone is child's play. Simply clean the screen and hang up the screen protector. Following the manual follow. Takes less than 5 minutes. Since I have not thrown my phone on the floor and have worked with a stone, I can not say anything about the actual stability of the protection.
