I recently bought a smoking everywhere e cig, it was $60 out the door with 2 batteries 1 charger and atomizer and 5 pack of low nicotine cartridges. i mainly bought it for my fiance who started smoking casually with friends, i quit close to 5 years ago to start boxing. How reliable is this brand and if i use it occasionally will it affect my conditioning even if i use a blank cartridge?
