At first I thought this thing was just broken then I figured out that you have to spin the front and rear sections to turn it on and off. Push button in the tail will not work if these are out of sink. Don't even think about using with the Mako foregrip/bipod. It works fine until you pop the bipod out- then nothing. You have to pull it out, reset it then have the same problem all over again. Worst flashlight I have ever owned.
Pros: None
Cons: Sensitive on/off controls
