First I want to say this place is awesome! I have been here reading non stop! About 2 weeks ago I purchased a Volcano inferno I havent smoked a cigarette since! I cant remember ever going this long without smoking a cigarette so im super excited right now! after reading some of the reviews I kinda regret purchasing it so I went out today and picked up a ego c twist and let me tell you im in heaven right now! im also waiting for my lavatube v2 to come in the mail and hopefully if my wife doesnt check our bank account and im still alive I will be picking up a provari in a few weeks. Now on to the questions, im a little confused on how to use a cartomizer can I reuse the same one for different flavor? or do I have to stick withe same cartomizer same flavor. I also picked up a mini viv nova does the same rule apply? sorry im axcited right, now I have more questions but I cant think right now!
