Had it for 18 months. Great aero (I've not windtunnel-tested it personally... :) Super comfy/adjustable. Visor is awesome - its position is great, doesn't touch my nose ever, full eye coverage obviously even when my head is down and eyes are all the way up. Hit a big tree branch and flew off my bike - chin needed stitches, but the rest of my head AND face were totally protected by the helmet and visor. When I ride with slower friends, I put my usual helmet & oakley sunglasses on 'cuz I don't want to show off my aero and speed obsession, but come on...just doesn't compare.
