And this point is total hogwash: Each cartridge costs less than $2 and is equivalent to an entire pack of cigarettes.
Equivalent in what way? In the number of puffs you can take, or in the delivery of nicotine? You might be able to get 200 puffs from one cartridge, but on a puff-per-puff basis, each puff of vapor delivers less nicotine than in a puff of smoke.
Also the cartridges pictured hold about 1/3 ml of liquid, and they don't say what % of the liquid is nicotine. If it's 16 mg / ml (1.6% nicotine) the cartridge would contain about 5 mg of nicotine, which is about 1/4 the amount of nicotine delivered by a pack of smokes.
But it gets worse. Later they state: "...along with 14 nicotine cartridges (a month's supply)." If a cartridge is equivalent to a pack of smokes, how is 14 cartridges a month's supply? All the months on my calendar contain a minimum of 28 days.
And further on they state: "7 Cartomizers worth 14 Packs of Cigarettes"
A cartridge and a cartomizer are two different things. Cartridges are used with three-piece designs (batter, atomizer, cartridge). Cartomizers are used with two-piece
devices that consist of a battery, plus a combined cartridge / atomizer.
Some folks swear by cartomizers. But I have never seen the
sense in throwing away a perfectly good atomizer just because there's no liquid left. IMHO, the only way cartomizers are worth while is if you refill them yourself instead of purchasing prefilled ones.
Spend some time in the New Members forum reading about various models. If you start off with a poorly designed e-cigarette, you will not be satisfied with it as a replacement for smoking.
