Geek Vape Zeus Sub-Ohm Tank is a newly designed leak-proof sub-ohm tank.  It comes with an innovative quick-change prebuilt coil system that creates the purer flavour and massive vapor with the GV mesh coil. Furthermore, the integration of direct top airflow and top-to-bottom airflow are available to generate big clouds and enhance nice airflow. With the top refilling design, you can be comfortable to fill e-liquid without dirty hands.
