The Innokin Thermo RDA is a stylish and beautifully designed RDA, with a unique look. This RDA has the look of a tank, But in reality, it is just a Stylish RDA. The unique look is to allow space for the Windstorm effect airflow, which is positioned at the top of the glass chamber, changing your vaping experience. The bottom airflow is non adjustable, but you have Mid-side adjustable airflow, giving you an impressive airflow to fit every vapers needs. With 2 pre built Clapton coils, along with the Japanese Organic Cotton, you have enough in the Thermo RDA box to get 2 builds before using your own wire and cotton.
