A Versatile HeadlightI use this light for work as well as adventures in all climates, it has held up very well and it so versatile. I can say that the "OS" you can get for it to use with your computer is a little useless, however at least you have the option. The auto adjusting beam it definitely one of the major perks, it comes in handy often and allows me to do other things instead of constantly adjusting my beam. Another feature I love is the ability to charge it off of my laptop as well as just jam some batteries in it if I need to.,,Over all it is a bit pricey, but in my opinion it is a well built light that will last for years.

I didn't realize how bad I needed thisThe reactive lighting is exactly what I needed. I can get 3-4 two-hour runs in on one charge.
Unfortunately my cranial shape and size is not well suited to keep the Petzl Nao 2 on securely the whole time I run. I end up having to adjust it every thirty minutes to an hour.
Other than that, I would say that the price is worth it. It's good to have the right tools for the job!

WOWSo far so good. It is being worn by my wife who delivers mail and sometimes must walk after dark. She says the light is brighter than vehicles head lights and she loves it. She also mentioned that others at post office have intentions of buying.
