Anyone use the Mares H.U.B.?

I've searched the site and can't seem to find anyone using the H.U.B. system. I know I'm a bit of a gear geek, but I've been intrigued by the concept of a completely integrated travel rig since I saw they were being released, and I just don't see them out there. Is it the price? Are they flawed in some way that i'm just missing? If you have one, please let me know what you think about it.
