Just got my HD Crystal for iPhone 5 from Tru Protection. I had been waiting for the one on the Power Support web site to become available. I used only Power Support Crystal on my iPhone 4 and so far this seems to be the same quality. Its the same company; The outside of the mailer says Power Support.
I used the steamy shower method and it went on perfectly with not a single dust particle. I did have a bunch of air bubbles which took a while, but eventually went away. It comes with a 2 part handy wipe packet (one wet and one dry).
Overall, satisfied for now, especially since I didn't screw up the first one have one to spare.
