Hey every one I'm new to the whole e-cig thing. I bought a riva kgo from north west vapors. I'm looking in to trying different stuff for it like cartos and tanks. I need something that I can fill and not have to fill again for at least half the day. But I need to be able to still just put my kgo in my pocket with out it leaking. I'm also wondering about the threads because I heard the different kgo's might not work with another brand kgo so I'm kinda at a lost of what stuff I can buy and what won't work.
