The E2 ceramic cartomizers.... Can you fill them without a syringe? All I've managed to do so far is make a mess trying to get juice down that stupid little blue adapter they package with them. There's gotta be a better way. Can I just walk into a medical supply store and buy syringes with real needles on them? Is there a way to get rid of the syringe altogether? I tried dripping in one.... all that did was run juice out the bottom. (Thankful for sealed connectors.) Any advice, tips or tricks would be helpful at this juncture.
