Familiarity: I've used it several times
The headlamp will discharge the batteries if left in the light more then a few weeks. I found this out the hard way when I had to finish up some hikes in the dark. I contacted Princeton Tec to see if I had a lemon and they told me to take the batteries out if I wasn't going to use it for longer then a week. Really?!? Hey, sorry guys my headlamp is dead, I forgot to take out the fresh batteries when I put it away.
