I have searched this and have not read a thread that exactly sums up what i need to know. I am currently vaping on a eGo-t with a smokteck dual coil cartomizer. I have no problems with it and I love every drag. However my wife just bought a joyetech 510 mega batt and a new 510 dual coil carto. I got it home and filled it for the first time and then topped it off. Every time I try to use it I take a nice long smooth drag and I get a burnt after taste. Can someone tell me what I am doing wrong or am I just trying to get to long of a drag??? Thanks in advance Josh
