I received my Maratac 1 X AAA Flashlight in the mail today. It is 80 lumens strong. I have made a few preliminary tests and I am very impressed with the strength in light of this little bugger. I am very satisfied.
Wow 80 Lumens from a 1 X AAA. That's quite impressive in my book. Makes my Fenix E01 feel under powered. 
The E01s strengths lay elsewhere.

It's "almost" unkillable and a true battery vampire.
Jors, is that the newer version or the original one? Did you get an aluminium or stainless version? My EDC for the last 6 months or so has been the ITP A3 AAA stainless flashlight (the same flashlight just with less knurling), and I love it. Still going strong.
