Massive badge premium with Rizoma. Most of their stuff is indeed style over function with a nought added for stupid boutique packaging.
Saying that, I've got a pair of Aero mirrors on my SF and they are bloody excellent and at the time were on a par price-wise with premium competitors. Only criticism is they sit a touch low and I tend to clack my knuckle guard on them when I go for the clutch. Still think they're some of the all time best made and best looking mirrors, but at a price. They weren't 400 bucks though...
