Very powerful lighting, and its battery lasts a lot with the use I give it, 2 hours a day, and with one charger it lasts about 10 days, very good!

Indeed powerful light. The battery life is not long, that is, 8 hours on low mode is a bit short because it is supposed to be a powerful light, so we put it on the high mode. Which means that in two days you will have to charge it if you ride your bike at night, of course. And if you forget to charge it, you're out of luck because it doesn't take batteries. Overall, I recommend it, you just have to make sure you have a battery or a charger.

Strong light and convenient attachment to the bicycle. After a small fall (it is mounted on the child's bike), the lens detached from its base. 3 days later, the lens no longer turns on unless it is plugged in and charging. 20 euros wasted.
