Beautiful bright light for night biking, but short lived circuits and fragile mount.
Initially light performed extremely well. Love the easy user replaceable Li-ion 18650 battery.
First issue I had was my mount broke (First the locking bracket, then the swivel base interfaceand t he light detached from the base). I was able to repair though with some super glue and electrical tape for reinforcement, mount is solid after those upgrades and not a reason for the reduction in stars. After dealing with all this, the circuit board just mysteriously died. Battery is in good shape at 4.1V, and from an inspection of the board I can't tell what went(No light when usb applied, switch is still functioning as multimeter ohm test proves).
Would love to still use this light, like some how directly connect up to the LED with a buck converter or some other custom solution to keep this light alive. I only had it for 4 months, used about 50 times total, probably 5 to 6 charge cycles on the battery, Wish I could just buy a replacement circuit board. Great light while it works, disappointed that it failed so quickly :-(
Other feedback, My light only had 4 modes(Bright, lesss bright, Blue, Pulse). Please get rid of the last modes, no reason for blue light(maybe red might be useful), also pulse mode? Prefer just a couple light options Bright and less bright mode. Also annoying to have to cycle through each light mode when you need to turn it off, would prefer long press option to turn off/on and short press to cycle modes.
