A mate bought one 3 months ago and says it is the best flip helmet he has used. He rides 15,000 miles a year commuting between Leeds, Norwich, Dublin and the Cotswolds. He was crafty and got his girlfriend to buy one first.
I bought a Neotec when M&P had them for £299. Only ridden 70 miles with it on but good first impressions. I like Shoei as they a) fit me b) are comfortable and c) last a long time
