As with anything that gets used over and over, it needs to be cleaned (with it being the atomizer). Don't you think the funk and gunk the atomizer filters out of the nicotine and whatever else is in the cartridge ( i think it's glycerine), should be cleaned, at least occasionally?
And, people, I repeat:
DO NOT submerge, rinse, sprinkle, dab,blot, rub, immerse, engulf, bury, pat, press, mop, swab, apply, stroke, bathe, drip, drench, splash, hose-down, clean or cleanse your BIONIC e-cigarette with any or in any kind of liquid, including any type of drinking or rubbing alcohol. Are there any questions?
The list of verbs, in a way, is a tribute to George Carlin. He was the best.
