The good Verabreitung, a clever (pothole and cobblestone tested) Bracket, lightweight (selbsterkärende, tool-free) installation, and the low price speak clearly for the lamp, which is also pretty small and loosely fits in your pocket. In town - generally on illuminated trails where there are seen around when comes to see itself, it is a good choice. But I radel regularly a completely unlit path, and then it will remain with this lamp, which is used by me in addition to the fixed mounted on the wheel front lamp, flying blind. The thing with the very focused beam of light is right and that is one reason why the lamp as a bicycle light, if you want to see something that is not suitable. On the other hand: Really good cost (lighter and more widespread) alternatives than fixed mounted light at least three times, operated as a battery variant also like five times. That not everyone likes to spend on a bike light (at an old cucumber). I did not want to even go and now for the time being in the (very) dark just a little slower. Conclusion: lamp itself is top, as bicycle headlights on unlit paths but a flop.
