Amazing light, low weight, don't even know it is on my helmet. My vollie house is looking to get them for the entire department. They basically took their tactical weapons light and made it into a helmet light. Then they added, the blue led on the back and changed the way the light works. But it is an amazing light.
I like mine but, the only issue i have is when i go to adjust it left and right, the screw loosens up inside then i have to take it apart to re tighten, does anyone else have this issue?
