Yesterday, one day later, the 1st coil went bad - at least I assume it was the coil. It started gurgling, the amount of air flow went up tremendously, vapor disappeared ...... Played with everything to try and fix it - checked the air flow screw - it had not moved, made sure the coil was seated correctly, etc., . Nothing worked until I put in a new coil and repeated as above. Everything then worked fine again.
Today the 2nd
tank did exactly the same thing.
This is not a gradual deterioration but a one vape is fine then the next is all screwed up.
This afternoon the 2nd
tank did the same thing.
I am using almost clear liquids in approximate 55 pg/ 45 vg on an Istick 30w at10-12 watts.
One replaced coil has been fine for 1 day and I just replaced the coil in the 2nd tank.
