I have used this on a 4-hour ride, it was still working at the end of that length of time.
The light works excellent, but that said, even with a full charge, the battery drains so quickly between uses that you need to plan on charging the thing before any sort of extended use.
I'll keep using it for now, but the next light I buy will be one I can throw my eneloops in instead of whatever garbage is in this one.
The light is very bright and visible for a good distance even on a bright day.
This product was able to charge but never turned on .
The instructions refer to holding the button a certain amount of time, but I've never found this to work, and so I don't have control over whether the light is steady or flashing.
This is a good bright light, but the plastic peeve that connects the light to the strap snapped off after 1 month of use.
I would have liked to write a review on this thing, but less than 20 seconds after I tried to install it, the plastic snapped rendering it useless.
I'm sorry I did not like to slide it only lasted about 20 minutes before the battery dulled out and had to recharge again will I ever get another one no way in hell need to upgrade it.
