This is a great little product. I bought it for the times I hike and trail run and it starts to get dark before I'm back. It's tiny, it's simple to use, it's super lightweight and it does a great job. I have tested it on trails at night when it is pitch black and I can jog along with no problems. I now keep it permanently in my Salomon Trail Vest. I don't even notice it is there.
You get 2 hours of reasonable light and then it goes into a reserve mode for an additional 1.5 hrs. However that is extremely low light.
There is one big negative and that is that it uses the old style micro USB.
I bought this at the same time I bought a Nitecore NU25 ultralight from Ultralight Hiker. The NU25 UL is similar at just 45 grams (not a noticeable difference). In my opinion it's a little better, cheaper and more efficient and runs on USB C. It runs a bit longer and brighter too.
