A great alternative to smoking cigarettes. I've been a cigarette smoker for 20+ years and this is the only thing which has helped me quit. I started off with the Vype E-Pen and cartridges. I would have happily stuck with that, only, the cartridges are not so widely available to me so I had to rely solely on ordering online via Vype. This had its pros and cons. Although the prices are similar, additional discounts are offered on bulk orders and there's an array of delicious flavours to choose from (pros); the courier company used by Vype are/were very unreliable (cons). My last delivery arrived bang on time, a day earlier infact, but I have had issues in the past. But coming back to the pros; the cartridges and e-liquid bottels do last a while, so I don't need to go through that palava often. Once a month at best. I recently switched from the Vype E-Pen to the Vype eTank Pro kit. Again, no complaints. There's no leakage so long as both the pen/tank are kept upright, and there's an even better selection of flavours for the tank. My only criticisms are that unlike the E-Pen, the tank doesn't switch itself off, the battery doesn't last as long and it also takes a little longer to charge. In any case, I wish such alternatives were invented sooner, I would have quite cigarettes ages ago! For anyone looking to quit the fags, I'd highly recommend vaping instead and in particular, vaping with Vype. Whichever device you go for, start off with the higher strength cartridges or liquids at first, then work your way down to the lower strengths. Good luck and happy vaping!
