Pros: Bulb Durability, Battery Life, Durability, Brightness
Great special purpose light.
Never had a problem, every surefire product I have ever owned or sold has worked 100%. Malkoff is still the best but surefire does make good stuff, if you want a light that will not break under heavy use or if you are like me and seem to be able to break everything just by holding your tongue wrong or something... get an American made light. Surefire sure is a fire option.
