Using as a way to switch and ultimately give up a thirty year nicotine habit. After using the e-tank for a week I've completely gone off the idea of lighting up a real cigarette. I'd recommend it to anyone who's looking to switch to vaping but would actually go a stage further and suggest that it's a good idea to buy two starter kits.... That way you can always have a fully charged spare battery plus you get another liquid etc. In the fullness of time I'll be dropping the down to the lower strengths although I'm going to remain on the 12mg until I'm completely comfortable with the idea.
