They have these little stands in the middle of the malls, telling people lies about there product. They say one cartrige will last for about a pack to one and a half packs of cigarettes per cartridges. I went home and followed directions and then I started counting how many puffs I was getting per cartridges. I was getting about 25 puffs to 72 puffs per. The next day the batteries stopped then the adomizer stopped working. I also looked on the internet and they said I would get about 20 cigarettes per cartridge. I get about 9 or 10 puffs per cigarettes. They said they would replace only the ones that aren't open. I don't trust a word they say. They would never let me talk to the supervisor. My wife and I were stupid enough to buy 2 gold kits. Thankyou [email protected]
