I had this case for my 3G. The glass was just like the iPhone glass, very smooth and lots of fingerprints. BUT, it wasn't the best quality, I noticed the glass started chipping. As far as the rest of the case, I loved it, it was my favorite case for a while. The one problem was the coating on the case seemed to start to fade away. It was kinda like a hard plastic case, with a rubbery feeling coating over it. It felt great, but the coating started to peel away.
From what I understand, they came out with a version 2 that was supposed to fix this coating problem. Don't know if it did, or if the glass chipping problem got fixed in version 2 either. If it did, it's an incredible case, I was thinking about buying one as well, no need for a screen protector.
