I have tried BluCigs, Green Smoke, and some cheap knock off. IMO Green Smoke blew the others out of the water. Though I was never able to kick real cigarettes and replace them with e-cigs, I still have mine around to get a few puffs in places where I cannot light a cigarette.
If you plan on trying Green Smoke you can get 10% off via this link and coupon:
