I bought this e cigarette at the mall at a kiosk in San Diego. The seller claimed each cartridge would be equal to about a pack of cigarettes. Each cartridge lasts MAYBE 3 cigarettes worth and the battery died on me after only 2 days and would no hold a charge. The flavors all taste the same and almost no vapor is produced. Overall its just a POS product that is way overpriced. read full review »
