7 totally changed over so far, and have 4 current dual users working their way toward 100%
vaping only. That's why I keep a variety of new starter kits/set-ups on hand when I find really great deals on them. I show/explain the differences in each set-up, how they each work, coil differences & costs, and they choose what they think is the most comfortable, a size they like, color, shape, style, etc. for them. I also start them off with 15-20mL of 1 of my DIY eliquids that they choose, after trying about 5-6 of them.
After trying vaping a few days or more...if they decide they like vaping and definitely want to stick with it...they pay me exactly what I paid for the set-up, and they get a free 30mL bottle of my DIY eliquid. I also let them know that if/when they want a new set-up, tank, more coils, etc., that as long as they're
still not smoking...I'll either have already or will find for them, the best deal on whatever they need or want.
Has worked well so far, doing it that way. Have had only 1 so far that decided it wasn't the right time for her to try to switch from smoking (too many stressful family things to deal with right then). Said she'd definitely like to try again though in thee near future. Wants to quit for herself and so she doesn't smell like an ashtray any more, especially when her grandkids visit.
