I took it for a good run today and i'm more than happy with it. I don't seem to get any buffeting at all and by using the very scientific method of holding my left hand out front of me i can feel the air flow about an inch over the top of my helmet. It is certainly A LOT quieter when riding and the stereo is only at half the volume that i previously used. As an added bonus i discovered that it also fits in the pannier too ( i didn't plan that).
