Hello everyone, new here! I have been stalking ECF for some time now and I must say I am confused with all the technical stuff. I have bought Ecig from china, however the drag have been hard and there is not much vapor. So I am trying my second order but decided first to ask some questions before I waste more money I have been reading on this forum about resistance and voltage and learned that this is what makes the vapor good. Can someone recommend some guides on this forum for the kr808d-1 model. I have been looking but could not find the best combination of resistance and voltage (you can ask the china company if they have this before ordering).
