Any tip on any device, do you really drip through them? I've vaped for 11.5 months now and this is one thing that I never really figured out. It's almost like I don't even want to ask at this point (lol). I even tried it once, adding juice straight through the hole at the "tip of the tip," on an iGo rebuildable. Just a messy mouth full of juice. What the hell? Am i missing something obvious?
