The amount of output and throw from such a tiny light is absolutely insane. It really has to be seen to be believed. This thing throws farther than other lights I have with significantly larger reflectors and brighter emitters. The UI is intuitive and complete. Great selections of modes laid out in a logical pattern, with direct access to moonlight and turbo which I think is a must. My only gripe is with the red led in the power switch - with the battery capacity being what it is, I'm concerned about running my battery down by carrying the light with the power switch led on. So, I loosen the battery cap slightly. This also wouldn't be much of a complaint if it weren't for the bright flash from the main emitter when the battery cap is re-tightened. In my opinion, if it weren't for the always-on red led in the power switch, this would be the perfect edc pocket thrower.
