Brandon McReynoldswrote a review of Petzl e+LITE Emergency Headlamp on September 20, 2017
Familiarity: I've used it several times
It's exactly what they say it is: a small, convenient source of light when you need it. You won't want to go spelunking with it or anything but it's compact and better than the dark. Not sure why they made enough headband to fit one of the aliens from Mars Attacks, but there's plenty of slack left over - I'd say that's the only drawback.
