These lights are bright and last for hours on a full charge. Price was good and shipping fast. I bought these for my wife since I liked mine so much. They are easy to clip on the handlebars or seatpost. One oddity is that the headlight uses a mini USB while the the taillight uses USB-C. This is not a major problem, but it does require two cables which come with the lights. Flashy modes make me feel more visible, and cars give a wider birth. The headlight is so convenient that I use it as my flashlight for many tasks.
I purchased this as a secondary set for the road or to use for daytime gravel events. They have worked well so far and lasted through an 8 hour race!
