Just returned my Elzetta last week. First I was underwhelmed by the output of the M60 and second the two stage high/low tailcap did not work as advertised. That is, on my unit it had to be fully tightened to be on high, a VERY very slight turn and it was back to low mode. Just too easy in my opinion to switch it to low- my Fenix TK11 is much more positive in this regard. I emailed the company and they said what I described was "normal". I'm not bashing it as it seemed very well made/durable and I may pick up the single mode model in future but wish they were a little more honest about how the two mode tailcap works. Perhaps the single mode with the newer M61 module would be a better fit for me?
