Hi. Few weeks ago was torn between the m150 and the m200. I couldn't decide so I ordered both. The tiny E3A was free to order. But I thought my father-in-law has a birthday, and such a tiny one is always a nice addition to a gift. So I ordered one. I shared the idea with my wife, she said it was great and she wants one too... so I ordered... and it won’t be my last one.
I love the E3A. The m150/m200 don't interest me much. I'd want a reflashable Anduril light instead of either of those: SP10 Pro, D2, or whatever.
