actually, while it DOES have many parts, there are very few you have to worry about.
There is a
juice flow ring on the bottom I have to get used to.
There is an airflow screw accessible only when you remove the 510 screw... Adjust once and forget.
The tank comes apart in 3 sections... But you close the
juice flow, and unscrew the mouthpiece connector, fill, screw back on and open the
juice flow... And vape.
That's all you have to worry about. Three pieces/parts, and one of them is set and forget.
If you want to rebuild, you close the juice flow and remove the bottom and it lifts out.. Juice stays in the tank.
