Got some Joyetech 510 B type attys for direct dripping. So many people here recommended them so much for better tasting the e-liquids that it got me curious. I'm looking at you, Kitsune. Now I have some questions. Sometimes when I'm drawing on it the thing makes a gurgling sound. There's only four drops of liquid in there. Am I doing something wrong? Drawing too hard? Do I need to wait a bit between dripping and taking a hit from it? How hard or softly do I draw from it? Does it matter?
