Thanks for all the posts, after filling a new carto, and lowering volt to 4.0 i am getting good vape and flavor. Would prefer more vape still though, but these are the standerd 5 box cartos. And yes it is definitely the learning curve, i agree. I am planning to order different juice from vapedudes i hear thats a good place. Can someone point me to a good website for new cartos and tanks. Also, a question about low resistance, should i use them? The only thing i find is the hotter it burns, the more irritated my throat gets, actually makes it hard to breath at times. Where i am at now 4.0 no issues, would just like more vapor.
