I hear that Phantomskinz are easily scratched. I know that they will still protect the phone even if they do get scratched, but then you still end up looking at a scratched skin for as long as you have it. Have you had any problems with that?
PS' site labels the product as "self-healing" from scratches, but from what I've read it seems as though even a moderately large/deep scratch manages to stay put. Other than that, PS skins are supposed to be great, but that was the reason I was initially turned off from them.
