Maybe also consider the TFV4...... the endless variety of coils with more on the way make it so flexible. Some reports of minor quality issues like o rings and chipped glass.
Herakles Plus. The only caution I have is the top fill system. If not done per instructions, the juice will wind up outside the tank. Great
reviews for clouds and flavor. I have and like the original Herakles. Nice flavor, dense clouds. Cyclone and Hydra got mixed reviews, so Sense needs a winner now.
My Crown is not getting much use. I prime patiently, but have not gotten much coil life. Have not used the RBA and hear its just ok.
Also, Uwell has not released new coils or other tanks..... Where Smoktech keeps innovating and Sensetech is trying.
