The Geekvape Ammit RTA is specially designed for the use of single coils. Geekvape has optimized the airflow so that it blows the coil from two sides (Geekvape calls it 3-Dimensional Airflow). This is the taste to spread much better. In addition, you have the possibility to regulate the flow of liquid by simply rotating the upper part.
The deck is not one of the largest, but there is plenty of room for even bigger windings. With 3.5 ml is also the filling volume large enough to indulge the steam pleasure.
