Worked great for about 2 months.
Used maybe 5 times for a total of ~3 hours. Then it would cut off or not turn on. Only way to fix it is to smack the side of the light opposite of the on switch. Also you can unscrew the cap/bulb section, and you will see a plastic ring with 2 holes. If you place a small pick or screw driver in one of the holes and press in toward the bulb, you will fill a spring in one hole. Press it in. This seems to help the cutting off problem. But it will come back at some point. Also I'd like the switch to be on the rear part of the ligh. This would help with inadvertantly turning the light on while in a pocket. Or they could inculed a sheath for the light?
It is a great light when it works correctly. Easy on batteries, and has LOTS of light.
Pros: Bright Beam and Battery Life
Cons: Switch / Contacts
