I have one but never used it much in AH. I was never happy with the resolution.
I found it difficult to read text and instruments.
I was not that impressed with the 3D and the head tracking didn't work as well as I hoped.
My plan was to mod it and mount it into a flip up visor arrangement and try it with track R but haven't got around to it yet.
I haven't tried it with the new version of AH. I really need to dig it out and experiment with it some more.
Frankly, my advice would be to wait for better technology to come along, but that's just my opinion.
Vuzix is supposed to come out with the VR-1440, with higher resolution but who knows when that will be.
