There are so many advantages sgp has over zagg 1) ultra crystal and oleophobic look and feel like the glass screen, except it's so much easier to clean and don't have to worry about scratching. 2) dry install 3) cheaper and comes with 2, if you need. 4) lasts way longer than zagg 5) no orange peel effect 6) No concern about yellowing effect I swore by zagg for so long, not realizing there were other protectors that were just as reputable. I honestly feel that if nobody has tried anything but zagg, they are just content with zagg because of history, which is fine. I'm just thankful for these forums, which is how I discovered sgp.
