It's a good light and this is my third iteration. The first one's battery stopped charging after using it daily for over a year. The second one's usb port broke after two years of use, likely accelerated by once or twice trying to engage the charging cable upside down. I was unpleasantly surprised to find out that the current version is still using a directional usb port whereas most competing lights as well as all the other electronics on my bike are using USBC. This means having to carry an extra cable and struggle to orient it correctly each time I charge it. Plus, USBC offeres faster charging times.
I loved it at first, but after about one year the flash function has failed and it only provides a strong, steady beam. Too bad. I'm now shopping for a new light and a different brand
The perfect light for the size. It's bright, lightweight and it could be used on the handlebars or even on a helmet (which is how I use it). I never leave home without when I ride.
