I have the new Z-Atty Pro V2.1 with the ceramic wick and this thing was working ok after i made sure the coils were glowing equally. It was at 1.8ohms so I then added juice and tilted and tested and it was ok vapor. Put the cap on and started vaping away.The coils were all good and working with no hot spots so i vaped the whole tank and it was good but not great. Filled the tank again today and now it just dosent vape very well at all and there are still no hot spots. I am vaping at 3.8 volts and even went up to 4volts on a 1.8ohm coil. This is my first Genny RBA and i am confused help me please lol
