ThunderHead Creations Tauren Solo RDA is a single coil rebuildable drip atomizer that features a 24mm diameter. It comes with a unique build deck, which has triple sides with 31-micro air holes to bring excellent flavor. Deep juice will prevent leakage effectively. What's more, it features a unique 3D honeycomb airflow system. The air comes in from side airflow holes and surrounds the coil to produce massive clouds. This RDA supports top filling and bottom filling.
