I'm a few months in on my vaping lifestyle, after smoking for 15+ years. I use a Aero protank 3 (pyrex), on a spinner and istick sticking around 3.8-4.2 volts. I prefer the sweeter Ejuices (butterscotch is my FFAVORITE!) at 70vg/30pg mix, just ordered more at 50/50 mix. I use the bottom coils offered.... (smoketech kanger...) my coils need changing FREQUENTLY. The juices clog them fast. Any better coils recommended?!?!
