I am looking into getting a new tank my Atlantis is burning my coils to fast even on a low wattage. I heard good things about the isub tank but I wanna know if the coils last more than a couple of days. So my question is how long do they tend to last? I need somthing that's going to last and not burn in 3 or 4 days tia! (idk if this makes any difference but I have a mvp 3.0 pro for my mod)
