Word to the wise for e-cig vapers out there, the evo can get very hot and if your mod isn't designed for the kind of heat it puts out, things can melt. Like the center pin bushing on a 510 connector... I would not stick one on a v1 Lava Tube, their top caps and atty connectors are known to be flaky with normal e-liquid vaping use, an evo would destroy it in no time!
I thought my REO Grand would be indestructible but that happened. No fault of the evo though, it's a pretty impressive little unit. Note: It took quite a few sessions before that bushing failed but now that I know it can happen I'll be looking at something that was designed to take the heat it can put out. (and getting my REO repaired :-P)
I'm with you guys on the longer warm-up times, totally. 10 seconds seemed incredibly optimistic after some actual use.
What impressed me was how effective it is once good and hot! It makes average schwag suddenly and dramatically much more effective.
TLDR: Evo hot, normal e-cig connectors can easily melt. I love it anyway. Vaping rocks.
