For me, the e-cigarettes provide a satisfying experience and are particularly convenient for use in the car and in places where people do not want the smell or smoke from normal cigarettes. The chargeable carrying case is also a useful feature. The one problem I had was with the tips that arrived in the starter pack which did not work effectively. I would have given up on the product at that stage had I not read another review that cited the same problem. I had therefore ordered a pack of replacement tips which worked properly and have continued to do so since.
