Well, guys, i just got my RIVA, but my cartomizers arent in yet... is there a good video or can someone help me on how to fill my cartidges? I tried one on my own. I took the cotton out, did 8 drops, then put the cotton in, let it soak a bit, then did a couple more drops to wet the cotton fully. then i put the safety cap on it, since i am still waiting for the riva to fniish charging. is this ok? can i do a bunch and leave them out?
