After having tried a few different ecigs in the past and always returning to cigarettes. I was reluctant to try it again. I am currently using a provari. Glad to say I have not smoked for a week and I don't have any cravings. Glad to have finally found what works for me. Pricey but it will even itself out pretty quickly. Cigarettes are not as cheap as they used to be he haha. Oh and the health bonus is great too
