I've had mine for almost 2 months now and use it everyday, I have version 1 that has no Ego
threading on the top (wich I prefer the looks of) and no vent holes in the cap, mine would vent flame and gas
through the button

I only use AW IMR 18650's and a LR atty so Im not concerned about it at all. Great
device and very versatile considering the different battery configurations. I love the switch, very boss indeed.
Thanks again for a great review that is entertaining and in depth.
