For my early morning commute, I picked up this light and love it. 300 Lumens is very bright. It has three settings, bright, brighter, and flash mode. I've only really used the flash mode and have done about 15 (45 min) commutes on one charge.
I like the USB charge. No batteries to worry about. Currently researching a usb charged rear light.
