Anyone else experiencing poor quality from the nautilus coils lately?.Ive been using the .7 coils and after a day the flavour declines and after that i have to keep reducing the wattage down..Though they're rated at 17w ive never been over 15 W.Fed up with the quality of aspire coils as this happens too often,OR is it to do with the donut kings manchester tart ive been vaping?Will put in a new coil later and try a different juice,then i suppose i will get the answer,its one or the other!
