I like my Busch Muller dynamo because it gives great light and most of all it stays fixed to my bike. This means no more fumbling with detachable lights and then trying to remember to charge then etc. The LED light is really bright compared to old style dynamos with incandescent bulbs in them. The stoplight technology is great as well, so that when I stop the light carries on for a few minutes. I always use the wire brush roller as it never slips regardless of the weather rain and snow. The only problem I've found is that the wire break after a year or two's use. I'm not sure why that is, but it does mean I have to buy new ones every now and then. Maybe Busch Muller can address this problem on the roller.
