Has anyone experienced problems like this using a K3 with the standard 1.8 Ohm Nautilus coils? I only got through half a tank of some (not cheap) Juice and now every hit tastes burnt and is producing some nasty smoke. Tried switching back to my old 70/30 juices but it seems the coil has been ruined! Coil was new in last week.
Would appreciate any thoughts/advice.
