The NEW Subohm steam engine from Joyetech! The new Delta II (Delta 2) evaporator from Joyetech promises a new quality of subohm steaming! The processing of the new Delta 2 is - as with all Joyetech products - excellent! The big drip-tip is of course interchangeable. The Delta 2 has a very good airflow control. A base for self-winding we carry as an accessory.
