Review on Yosoo Hat Clip Light Lamp /Light / Head Torch / Head Lamp, 11 LED, For Fishing, Running, Camping, Hiking And Mountain Climbing by Chris Hunt

I run on trails at night, and this little light is bright enough to easily run in complete darkness. Definitely worth the $7. I'm on 6th run with the original batteries, and they have not faded. When I got this light, I was unimpressed by the build quality, and plastic hat hooks, but I have had no problems using it. The hooks hold onto the brim of my hat solidly, and it does not move around. My only complaint, is that there is a tiny bit of light leakage through the battery lid, which only affected me on the darkest nights. This was easily remedied with a bit of tape.
