I've had this thing for about a month now and am amazed at how small and bright it is. It's smaller than your thumb and brighter than my trusted megalights!
It needs to be attached to a key fob or you'll lose it for sure.
I use it most nights as we walk a couple of miles for exercise, normally after dark since we live in the deep south. (Posted on 6/7/14)
The NANO light is small enough to make a nice key ring light and not be bulky in my pocket all day long. At the same time, it is intensely bright and could be used for most any task including distracting a bad guy if need be! A good value! (Posted on 12/27/12)
I've never really purchased a pen light because most of them that are decent in terms of illumination are too bulky to fit on a keyring. The ones that are really small tend to be underpowered and worthless. The Nano Light is super small, but really powerful. I keep it on my keyring and don't even notice it's there until I need it. My headlight came apart on my bicycle the other night out in the middle of the woods, and the Nano Light was the only reason I was able to find all of the pieces in the small grass, thus saving my ride. Get one! They're worth it! (Posted on 11/14/11)
