Me llego a tiempo, eso deja bastante calificación buena para el vendedor, al recibirla me gusto mucho, se mira fuerte, funciona tal como se muestra, habrá que probarla, ya iré comentando mis experiencias. Ya he salido con ella y me funciono muy bien, enciende la luz de stop cuando me detengo, en el modo inteligente funciona muy bien... EXCELENTE, me a gustado mucho, el vendedor dice que la marca es SHANREN, pero entre en la pagina de esa compañia y no la pude encontrar, en la caja que viene empacada dice que es ENFITNIX, es por eso que le quito una estrella.Compradas el 30 de noviembre y aun siguen bien. Excelente producto, de hecho compre otra

The thought of the smart light is good and its great being able to leave the light on my bike and not mess with the on off switch. Brightness seems ok, nothing too bright and does the job.I do have one thing to add for improvement though. I have to unscrew the light when I lock my bike outside the gym to prevent theft. It is often hard to get the light to screw back on especially if I have full gloves on. Reason being the light is under the saddle and the teeth on the light is a bit fine, so it requires a bit more precision to screw on. It would be better if there was a way to snap the light on.Battery life has been good so far. At least 4 hours and counting.
