I saw this and thought it was the same model I owned, but it isn't (mine is the XT11GT). Even though I can't speak to this particular model, I will say (because it uses the exact same "shell," with the only difference being that the place you attach power is just a button on mine, and mine has a water-resistant rubber flap covering for a microUSB jack instead) that Klarus's flashlights in this style certainly come in handy more often than you might think.
My only real gripe is that I wish I could reposition the belt clip near to the head of the light facing in the opposite direction. That would actually make it so that I could clip it to one of the pocket flaps on my cargo pants/shorts to be able to use it "hands free" to light my path when I'm trying to take out the garbage late at night (when my procrastination finally breaks down). Other than that, I find myself using it on at least a weekly basis, and I only have to charge it once every couple of months (though, I did purchase a chipped, higher-capacity 18650). I never really have to use the 2000lumen max brightness, either... generally it is set to the second-lowest of four settings, so in retrospect this 1300lu model would have been enough for my purposes.
If I had need of another backup flashlight, I would join this drop.
