I agree, Klarus makes nice torches.
Their UI, strangely, works for me and I wouldn’t imagine that before I tried it. It’s easy, small button = momentary on, starts on low and with every tap it switches to a higher level. Though, I would sacrifice “momentary on at low level” for “tap on and immediately accept fast taps to next level”, I think it would be very intuitive.
Big button is turbo and works great, momentary on, one button, one job, the one you will most probably want if you need light fast.
I think I have a misfunction on my XT2CR, which I am not sure yet if it’s my fingers fault mistakenly clicking the secondary switch along with the main switch or a driver fault. When I press the main button for momentary on, after a certain point, it switches to low and stays there even if I click the button on. I would like to know if that happens to others too.
