I bought an aluminum Element Vapor Pro and it has no problems. I actually got it to see how it fits in my current Kickstarter project, the Elevation Dock, b/c a lot of people asked and they love them.

It has plastic around the top left corner and small foam pads so the aluminum never touches the steel antenna. If I were these guys, I would machine out the corner and make a polycarbonate piece to fit.

If anyone here has one, I'd machine the modifications for you just to show it.
