The nic level seems too low to be of much use, and other than stealth vaping, I don't see why someone wouldn't want the vapor. I wouldn't say it is a scam, per se. Unlike so many others, it doesn't seem to be overpriced for what you get... it just doesn't seem to be a very good quality product. Of course without actually using it, I couldn't say for sure. But I probably wouldn't use a vaporless ecig, so I'll probably never know.
Actually i think that I figured it out...2mg nic is too low for an all day vape, but it's perfect for a single cig...maybe these are one shot carts, lasts 5-6 minutes and then dead.
