I've been using Zagg since I got my iphone 4, but I've had so many problems and replaced it so many times (5+) due to it peeling off from the corners I finally gave up and tried something else. I put the Ghost Armor on a few hours ago...a quick list below outlines my thoughts, for anyone interested in trying something different: Zagg: Pro: Comes with spray, no need to make your own application solution Pro: Fingerprints don't really stay and are easy to wipe off Neutral: Somewhat tacky/rubbery feeling. Could be good or bad, depending on personal preferences. Con: Slides around on the device after some use, edges are prone to peel off Con: Orange peel texture visible Cons: Turns yellowish after some use Ghost Armor: Pro: Seems to adhere better to iPhone, seems "solid". Doesn't feel like it'll peel off. Pro: Cut better/more precicely Pro: No orange peel visible Neutral: Feels less rubery, more plasticy Con: Have to make up your own application solution Con: Perhaps blocks some light? Maybe it's just me, but I had to turn the brightness up slightly to get the same brightness as with the Zagg Con: MAJOR fingerprint magnet. Fingerprints don't really wipe off well either, just smear around So far, I definitely like the Ghost Armor better than the Zagg, minus the fingerprint situation.
