SGP:I really don't know how much better Power Support can be then the SGP Crystal screen
That's just not true. The SGP films are hard like PowerSupport (at least the Steinheil and the Ultra series). They ARE reusable and removable. I took one of their Anti-Fingerprint protectors off of my iPad and reinstalled it (I decided I did like it on there after all).SGP:
Soft Adhesive Film, not reusable, harder to install
Hard non-adhesive film, resusable and removable, very easy to install (you get as many chances as you want).
I have a very hard time believing SGP's soft film can even be on the same planet as far as "glass like" appearance and feel as Power Support's hard film. I'm not saying SGP is a bad adhesive film, because it isn't. In fact it is the best adhesive film out there...but these types of films don't do it for me.
