lol, I'ld say it's more a progression in the vaping process. A few months ago, I never would have considered a TANK! It's simply a matter of finding what works for each of us to keep us in that happy vaping place. Then when you think you're "mature" Vapor4Life comes out with new stuff.
Mike Roper - totally agree with you! There's plenty of time to progress into all the options out there.
