That's known as dripping- drip a few drops on the atomizer/ element and vape. Great vape BUT have to constantly re drip on the atty. Also good attys are very expensive and they need to be cleaned regularly. See my earlier post about diff delivery systems.
Hey I found this video on youtube, from someone on ECF Cartomizer - Cartridge - Drip Tip & The Difference - YouTube. She is using an Ego, but I'm not quite sure what she has on top of it? I like the setup she has. Is the entire top the drip tip setup? Or is it just the black plastic bit on the top?
