The Zagg protectors are great! Very easy to put up with the little spray supplied in the kit, no risk of bubbles or dirt. Protection quickly arose. My Xperia Z is protected with for over a year, I work in the agricultural environment and practice a lot of outdoor activity, protection is still in a new condition. The film not naltère quality phone display, plus it is very sensitive to fingerprints. Too bad there are no proctections slices of the phone to protect it completely
