Interesting, different take onscreen protectors. I like that there are hardly any bubbles or placement issues, and it's easily reuseable. It only sticks to the bezel. Nice idea, someone try it!
I did read that some used it on iPad1. Hadn't heard of this approach before. hmm. Could be a good option to Power Support AntiGlare.
Cultofmac gave it 5 stars today. The Amazon reviews are 124 glowing.
