Bought one. I like it. Doesn't add a lot of bulk. I also did just order a case from crown case or case crown (don't remember the name again). Both are just "wraps" where they snap on the back. I keep my phone naked with an IS on the back. These are the first cases I will be using.
Overall, I'm happy with w/the metallic case, but ordered to other just for a change of pace sometimes.
