I have 2 of these (and 4 other SureFire weapons lights) and they are all great. I love the high and low beam setup. Low is plenty bright and lasts a long time. High is very bright for when you just need that extra brightness. Love the tactical push-button switch on the back, especially when using a handgun. One switch (momentary push button)operates both settings with added pressure, and twisting the back will switch both modes on without having to push the push-button. Solid feel, quality construction!
Pros: long lasting low beam, high output high beam
Cons: a little pricey, but worth the money.
