I have one which I used over the last winter on my Speed Triple. For the price, I felt it was good value. Only thing I don't like is the drop down visor mechanism. I could not get the hang of sliding the small sprung loaded latch across the top of the helmet. It is the only flip front helmet I have owned, so can't comment on how it compares against others.
Went back to Shoie GT Air, which for me just feels right in every way.
