My helmet came in earlier this week. I've had 3 days of commute time and so far, it's a world of improvement over my HJC. Ventilation is much better, I can actually feel air moving around inside. Field of vision is better, easier to glance back when changing lanes. Fog is not a problem, the breath guard helps and with the better ventilation any minor fogging at stop lights goes away instantly. I haven't had to crack the shield every time I stop.
Noise wise, it seems a little quieter than the HJC, but still need and use earplugs. According to major review sites I have seen, there is no such thing as a quiet helmet.
Quality is top notch, up there with Arai and Shoei.
Sizing and fit: need one size larger (i.e. I normally wear a large, ordered the XL and it fits fine). Fit is for "round" heads, like Shoei.
Great deal going on at Center of Gravity ($199).
