Bought a Power Support crystal for my iPad and got it on perfectly, except for one piece of dust, tried to get that off and smudged the adhesive and just gave up. Eff it. It looked like crap after that and no coming back. My advice for people wanting to do this. Find something like a CDC Clean Room and put on one of those Andromeda Strain jump suits before you even open the package. couldn't believe how much crap alit upon my screen as I tried to apply that film. God I'm a moron.
