So although some people here have said they are bad for the e-cig business, they have their place. If for no other reason then to introduce people to the world of PV's as right now its quite a niche market that most people, smokers included, have never even heard of. And the more people know about vaping the better.
I have to agree here. These guys are out there all day, every day introducing people to the product. If nothing else, maybe it will make someone say "Oh that's just one of the e-cig things they sell at the mall" when they see us vaping indoors.
