Hi, I am currently using NRG SE mini tank with my Vaporesso Swag mod. 3 months now. Until recently I've had no trouble with all the coils be it GT2, GT4 or cCell. But now, no flavor. Good cloud, no burnt taste either, just no flavor. Weird thing is, when I open the cap and close it back again, take a hit, the flavour is there. But after one or two hit, no flavour again. Also using juice that I've already tried and enjoyed before, mind you. I already did the following:
1. Changed to new coil
2. Cleaned the tank
3. Using the tank with different mod
4. Changed glass, and all the rings
Help me.
