Well, it is small. It certainly won’t break your back when you are out hiking. The Nano is made from aluminum, much like Maglite® flashlights. It feels solid and well-made, which inspires confidence. The design is clever too because the LED is recessed in a concave housing at the end of the light. Somebody definitely put some thought into this little light. Speaking of light, the Nano sheds a lot of it! This little unit generates 10 lumens, which is a decent output from such a small unit.
