Have yet to see one in the wild, but GTN did an infomercial on one recently. I have been told it "tests fast" and might work well for me since I have a huge gap between my back and any helmets with a tail. That said, $500 is a pretty steep price tag for what looks like a very hot ski helmet. Didn't see any recent discussion of the helmet in the forums, but did see a recent thread about the ARO3 & ARO5.
