Thanks all! I'm using 50/50 juice. I understand that all cartos need to be kept wet. But, I guess I don't understand the reason to have Mega size if you have to top it off just as much as the regular size.
The dual coils I got from avidvapor don't need to be topped off as much. They're not quite the same as a Boge LR, but pretty close. Ikenvapes are closer, to me, but I have to top off too often.
I'm a very heavy user as well. Are you saying smoktech is making the ones avidvapor sells too?
