Have a Fly Trekker, bought it for my trip to Vietnam last fall. Find that its one of the most comfortable I have owned and definitely the best value in a helmet. Was going to by a new street helmet but it works really we while riding my connie, so I think will just keep using it.
So if it fits your head, its a good choice. Some of the concerns that have been mention here are valid. Little funky with sunglasses, but that is easy top get use to. The visor is either an open or closed the first detent is right in the middle of my vision. But this is minor for me, for others it might be a problem. But for the money its hard to complain.
