'Flavor wick' is a term that we started using for the extra wick/s that are loose on top of the coil.
We just coined them that name as most
devices had more flavor with them rather than without.
You can easily remove or add them depending on the thickness of your
juice. To many and you can get dry hits or not enough and you get flooding.
Most kanger
devices ship with 2 flavor wicks and for me personally, 1 works great.
