adequate but not great for night running
This headlamp is suitable for slow going, or surfaces that are not irregular. Not enough light to safely trail run at night, and barely light enough to run on the road (assuming no street lights). For night hikes or walks it works fine. Seems sturdy enough, and easy to use though the buttons might be difficult to manage with gloves on. It could also use a focusable beam and it would be nice if the strap were easy to remove for washing. There isn't really anything better out there though.
