Lasts more than 4 hours, strong built, multiple flashing options, no complains.
Thank you BOTS.
This is absolutely crazily bright. Easy to install on bike bag or tube at right angle.
It's an hassle free and long lasting product with multiple modes. It's long life saves the cyclist the hassle of changing lights in the middle of a ride, accordingly it's more safe too.
Looks great, plenty of modes to choose from and battery lasts longer than expected.
