So far it works very well - used on my MTB, on fairly non-technical trails. The battery is quite light and lasted more than 2 hours on a full charge (and test discharge) at maximum settings. The construction is very solid and the water resistance looks good. Driving on wet/muddy trails can of course dirty your flashlight :-(Long pressing it for storage or travel will "lock" the switch so you have to long press to turn it on - so it won't easily turn on turns on If you bump into a pocket The handlebar mount doesn't work very well for me as my arms are different widths and right where I want to mount the light the arms aren't the same size so the light hits a bump can move (into the narrower part of the handle) and then loosen and move, I have to push it back to tighten.. if that helps.. I bought the helmet mount separately - I don't really like it (I'd give it 3 or 4 stars), but it will work just fine.. Your helmet.
