I have figured out a good way to refill the v5:
1. Close AFC ring (close off airflow)
2. Remove top cap and o-ring
3. Fill via either hole (I use a blunt needle so either works)
4. Refit o-ring and top-cap
5. Turn fogger over (upside down)
6. Open AFC ring (open airflow) -
juice will run out via drip-tip so have a cloth/towel ready
7.
vape on!
