Help! I am so tired of refilling these cartos and they aren't even lasting a day so I need something to remedy this. I use the KR808D batteries and I need to know is there anything I can buy that can allow me to pour juice into it and just screw it on this battery, if so please tell me what it is. I have seen a few different starter kits with different systems but i'm very comfortable with the type of battery i'm using because it feels like a real cigerette but this cleaning and refilling cartos is getting to be a bit much, plus it seems like lately all my smoke is tasting burnt after a few hard pulls, no matter what flavor I use. Especially if i'm smoking on my passthrough, not sure whats causing this I guess it's getting to hot and the juice is burning. I don't know..can someone please help me out!!
