Its actually pretty good, I'm getting a lot of vapor and a good throat hit. If your serious about putting down the smokes you should check it out. You can learn a lot from ecigaretteforum.com
I got it a few months ago,don't puff on it all day..I still use it when i am in the house at night.It did help me cut down from a pack a day to 1/2 pack a day.
