I have a smoker friend who has tried my V2 cig-a-like a couple times and liked it. That's all I've been using for a year. On Monday (I hope) my Provari and ego twist will be arriving in the mail. I was thinking I might let my friend borrow the ego for a week to show him what decent vaping is really like. What I want to know is, what would be the most user-friendly apparatus to put on top of the twist so as not to discourage him in any way. I have some boge carts. Should i just give him a couple of those? I'll provide him with good juice from HHV and teach him how to refill, charge and all that.
