Price and performance are OK. The lamp is easily recognizable and a quality image. The LEDs emit all off in different directions, so that one is recognized by an oblique rear well. The mounting is also possible on narrow or wide bars. But as some of the previous speakers I do "just in case" and still there a cable tie. The battery indicator is simple but makes for a roadworthiness approval. It if lawmakers finally waived the weight limit for battery lamps would be nice. On my MTB do I receive in the frame neither a dynamo off, nor do I want to have a turn. Here equal rights for all would be nice. My bike weighs 14 kg, unfortunately, too much for the current official Verkehrszulassung with battery lamps .... Corrosive.
