Familiarity: I've put it through the wringer
I can't tell you how great this headlamp is, you'll have to buy it. It's been with me in below-freezing temperatures, and it's help me get out of pitch-black timber in North Idaho. This hunting season I didn't realize that I had dropped my EOS in the timber, until I found it 6 weeks later on the trail. It had been buried under snow at 4500 feet for 6 weeks, and still worked perfectly when I picked it up.
Like I said, this is the best headlamp for your money.
