Pretty good, but not as good as the starter... Bought this as i'm sick an tired of smoking. It gets me down when i'm sitting here coughing my guts up over a little white stick, so I decided to try something new and I found this is in my local shop. At first I was hesitant and didn't think much of it but then I realised I had gone 2 days without a smoke (I normally smoke 15 a day). Then came the point when it ran out on me so I had no choice but to revert back to the cigarettes. A couple of days later I bought the Starter Pack from this website and haven't smoked since! Try this, if it works, buy the starter pack!
