I'm sure you heard them talk about the "atomizer" or "heat coil" on the e-cigarette you bought. Won't you won't hear is that this piece requires maintenance, must be cleaned, and is prone to failure and short life if not 'babied' ad taken care of.
The new tech in the 2 piece means that the atomizer is actually built into the replacement cartridge. So, every time you change the cartridge, or flavor, you get a brand new atomizer.
The only thing you actually hang onto is the battery for recharges. — May 8, 2009 5:09 p.m.
