Wotofo has just introduced the brand new Faris RDTA/RDA. This unique tank allows the user to convert from a RDTA to an RDA with just a plate change. Yes, it’s that simple and but that’s where the simple stops. the Faris has a few unique features including a built in adjustable airflow control in the top cap as well as a deck which supports both single and dual coils. If that wasn’t enough, the Faris also has a built in one way fill valve called a “Duckbill” which does not allow any juice to escape after filling.
