Yes, I have one, it was a cheap and cheerful out of Netto/Aldi or similar and it's been great. I think it was £6.99 a couple of years ago and it's fine. Decent life from a minute or two's winding, and it runs both lights. The whole thing folds up small and fits in a pocket, it's a good get-you-home light for summer/autumn evening rides. I wouldn't want to use it on unlit roads, I'd want a halogen or modern high power battery LED light for that.
