By "more complex" let me give you an example:
You are out in the dark (let's say camping) completing a closeup task while at the same time trying to preserve your night vision. You are using your M1X at its minimum setting of 10 lumens. You hear a crashing sound in the woods nearby and want to go to max with your light immediately - it could be a bear...
With the M1X all I have to do is tighten the head.
With the TK30, if I'm in the 12-lumen mode (output A of Camping Mode), to get to max I would have to tighten-loosen-tighten-loosen the head within .5 seconds to get to Hunting Mode and your max output.
Now the "noise in the woods" has gone away and I want to get back to my minimum setting again.
With the M1X, you simply loosen the head a bit - and you are done.
With the TK30, you need to tighten-loosen-tighten-loosen TWICE more to cycle out of Hunting Mode, through Searching Mode and back to Camping Mode.
So, would you say the UI of the TK30 is the SAME as the M1X in this case, or a bit more complex?
