I have had from the worst to the best in e-cigs and have been vaping for around three years (disposables, generic cheapys, screwdriver mk1, ego-t, go-go, provari ...). I always seemed to go back to analogues at some point, but since buying the ProVari and having to justify the spend in analogue savings the final transition has been made. Down from 20 a day to maybe 1 every three days. The new toy and supplies will be paid off in less than two months and every day I feel less of a need to pick up a toxic log. I guess what I am trying to say is spend your cash on the best equipment you can afford, buy a high maH device and have a bag of willpower to see it through. My advice is to try get a battery mod setup and keep one battery in use, one as a spare and one on charge. My setup lasts almost two days on a 2500maH good quality battery, so even if you a vape excessively a full day should be no problem.
