On my third season with a Chinese Valeo clone on my V50II. Cheap and cheerful, fits perfectly, delivers more starting power per amp because of the planetary gears. Faultless to date. Possibly a real Valeo might last longer, but for $75 I can just replace it if there is an eventual problem. Another bonus: The clone is significantly lighter than the Bosch, so you gain several pounds the bike does not have to lug around. Win-Win in my book.
