1st i want to say sorry if this is a dup. question. I have read so much and watched so many videos in such a short time my heads spinning . been vapein 1month 6 days- 13days smokes free. what I don't understand are the coils in the adjustable airflow tanks. have nothing to compare to-- only have nautilus mini for 9 days. coil that was in tank started tasteing funny after 1 week broke out spare that came with it. didn't even get threw 1/2 tank & it was the worst thing I ever tasted in my life. no its not a clone, real deal. and yes I primed it. most of you guys know what your talking about any help you are willing to give me I would be honored. oh I went threw all the spitting and e-liquid and burnt pieces in my mouth. Are theses coils safe? what other choices do I have in coils? b/c if I can learn how to straighten this out I would like to get the other tanks for nautilus mini. have lots of ??? anyone?
