I have been using vision stardust cartomizers on ego c twist batteries since I started vaping. I buy juices like crazy and I've heard a dripping atty is the best way to sample new flavors. What is it? Looks to be made of several components and I still can't figure out what they are supposed to do. Can someone explain the concept? Can someone just tell me what I need to buy to make this happen? I've been trying to figure this out comprehensively for two days. Please help me!!
