It’s one of those lights that might make none flashlight people very happy - my wife, who is not at all interested in flashlights took the lights in her hand, played with it for 5 Minutes and for the first time ever she asked if it could be hers after testing.
I liked to carry the light on my office days, as it brings all you could need and disappears in you pocket so you nearly couldn’t fell it.
I know Ultrafire from the old days and can tell you, this is on a different level. Quality of the machining and electronics are not only up to date, but on a really good level.
