I just purchased an e cig for my girlfriend...
I cant remember the name of it off top of my head but i believe it was E CIG.
She smoked like 4 or five times a day, and now after 2 weeks she has not had a real one since. I strongly recommend them . I have an occasional cigarette myself and to me it was exactly the same thing and even curved my craving for a dip.
The cool thing about the one i got her was that i came with two rechargeable steams and they 12 separate cartages. The cartridge is like 400 puffs, which is great because for her craving she takes like 4 drags max. Then once its out you can add drops that are Ten dollars for 40 drops, and 5 is a full recharge.
The biggest plus other than the fact that you quite is the money saving factor. Its just money in the bank.
I hope it helps, if you need any more advice or specs hit me up in a PM.
