So I am new to the vap and have been vaping for about 10 days now. I started out with a twist and have already moved up to a silver bullet. I have found that the 6ml dual coal cartomizer has been a simple way to keep going without too much attention while on the move throughout the day. So far this has been a great way to stay off the cigarettes today being day 14. I am enjoying all the different juices and learning about this world that I had no idea was out there!
