VandyVape Bonza V1.5 RDA is an upgraded version of Bonza RDA, which is also designed by The Vaping Bogan & VandyVape. The Bonza V1.5 RDA continues the exquisite carved of V1.0 and improves the performance. The Bonza V1.5 RDA enlarges posts, screws and plates to make coil building easier. With the new dual AFC options, the RDA could bring smooth and excellent airflow. It also includes a raised squonk pin to support bottom feeding. 9mm juice well and top cap locking system avoid leakage effectively.
