Good thing it's a 3 pack, because it requires practice!
It is extremely difficult to get this installed dust free. You better plan on sacrificing at least one of the three protectors just figuring out how to do it. My first one was completely wasted because it somehow got a crap load of dust under it in the second between cleaning it and putting the guard on. The package did not include the cleaning wipe that it said in the instructions would be there. It only had the dry cloth. Luckily, i have some glasses cleaning wipes that work well. My second try went a lot better and only got one tiny piece of dust up by the ear speaker. Irritating still, but at least it isn't out in the screen anywhere.Once finally installed, it lays down nice without bubbles around the edges like you get with the tempered glass protectors. (what got into apple's brain making a screen that isn't flat at the edges?!) unfortunately, this cover is just much harder to install than a tempered glass one.
