I'm so happy that I purchased another cig last night cause today both complete set ups are just not Working! One battery keeps on turning on in my pocket and gets real hot, and the other battery didnt charge for some reason! One of my cartridges has foam issues and all the juice keeps disappearing and I am almost out of my portable supply. And the other cartridge is only half full with a different flavor that does not mix well with others! Another bad work day and I'm praying that I have enough to get me home!!! This is gonna be tricky. Hope the second half of the day isn't too brutal like the first half. (oh yum, now I just got a mouthful of juice that should have been smoked!!!)
