I have three of them waiting to be used for a gimbal designed around the Red Epic. They nicely made and strong. They give a cleaner appearance than the CF mounts I've seen and they seem like they'll protect the motors more.
Neill is awesome to work with. Some of the best customer service I've experienced (which seems to be a rarity in the multirotor world).
I'll be doing a build log once I get a control board in.
I should have a write up next week. I have everything put together, I just haven't powered it up yet. Everything is nice and smooth, so I don't think I'll have any issues.
