Sorry for the silly question but I only have experience with clearomizer and genesis. I can recoil/rewick the clearomizer now, but can't get the genesis works, so what other choice can I have to get more vape? Searching the site a lot, I see the next thing I want to look into is the carto tank. If I am correct, the carto tank is simply a tank surround the cartomizer. My question is if the cartomizer can be recoil/rewick like the clearomizer? Is the coil inside the tube? What other part is in there? Spongy, cotton? Thanks.
