I put on the ZAGG invisibleSHIELD for enTourage eDGe (Screens) last night, it was easy no problem, the covers fit great, just remember to spray your hand really well and the screens. I started at on corner and came across so it lined up well then I used the squeegee, and it went down well, I then let it dry over night and it looks great. I can barely see the screen covers.
I have seen no difference with ether screen as I use them.
