Okiedoke...Fosman has arrived, and I AM impressed. It's noticeably thinner than the Diz, which feels a bit more rigid. The Fosman also has more gloss finish around the margins and curves of the phone, so it feels softer in the hand than the Diz, which has a ridge or seams of transition between the matte and gloss finishes. I think the Fosman TPU, while slightly thinner, should offer similar protection from drops, feels more pliable, softer in hand, but has a few mold marks and isn't as perfectly finished as the Diz, but then is a few bucks cheaper than the Diz. Both are worth the money, either way!
Edit: I'm also noticing a difference in the matte finish feel between the backs of the two: The Diz feels like a smooth rubber, while the Fosman feels a bit coarser and more like textured plastic.
