Both lights are fantastic in this package, it's hard to imagine anything better. The handlebar light's directional beam is fantastic and the hangover compliments it very well on twisty single track or uneven terrain. The battery and adaptive lighting / duration is very good. At ‘low’ I'm able to ride without issue to and from the trail at night, and medium is more than enough to see the trail. I use adaptive (high-medium) mostly since my rides are usually 1-2hrs and has a lot of terrain changes and twisty singletrack, I’ve never had an issue with the lights. Big jumps / drops can cause the handle bar light to point down or up slightly and need slight adjustment after landing, but its never a problem on rough trail and not often am I hitting the park at night. Would buy again and told a few friends to look into this package, customer service is also next-level.
