It appears I am a scoche late to this party:-( I would very much like to know if anyone here has any semi long term insight about the Mig 21(say, a few months of fairly steady use). The thing is, I know someone who would love to quit smoking but has failed at every attempt. Since vaping stopped my cigarette habit in it's tracks after 21 years, I thought it might work for her as well. She once tried a Kwik-E-Mart cig alike and thought it was horrible. She could taste the filler in the cartridge. She flatly refused an ego. Too conspicuous. I thought the Mig21 might be the perfect solution but I want to be sure it will do the job long enough to get her past the point of reverting to tobacco. She will never buy a kit when she could buy a carton of smokes for the same price and I cant afford to spend the money on something that will collect dust. Anyone have any input?
