This is far and away my favorite light for work. Simple, powerful and feels solid in the hand. My only minor gripe is the UI. It would have been nice if mode switching required say "3 quick momentary presses", or something along that line. As it is, if you press momentary again within about 2 or so seconds it switches modes on you - slightly annoying, but it's easy enough to switch back. It was really a bargain while they were closing them out too. If you can still find one, I highly recommend it.
