When the e cigarette is fully charged and has a new tip then it is a reasonably good substitute for a cigarette and a considerable improvement over the previous generation of e-stick. The tips however are a little too expensive and do not last long enough. Over their life they quickly become less satisfying. Not too many retailers stock the Vype e cigarette tips and those that do charge £8 a box. Tesco for example rarely have any in stock, or if they do only very small amounts of stock. E-cigarette smoking needs to be cheaper than this. £5 should be maximum per e stick re-fill pack. The e pen product is much better but again £5 per box of 3 refils should be the maximum retail price. I love thr products though. Keep up the good work, but keep them as safe, health wise, as you can. Paul Bawden bawdenpaul@hotmail.com
