The Wotofo The Troll X RTA marks the advent of more innovation by Wotofo to make your vaping experience a whole lot better. You can expect greater flavor intensity, better airflow, and enhanced overall experience with the Wotofo The Troll X RTA. The Wotofo Troll X RTA comes with an advanced inflow air diffusion solution through the honeycomb structured slots. As the air flows through the RTA, the honeycomb slots distribute the air and surround the coil with even airflow to improve the flavor intensity you get with the RTA. The Wotofo Troll X RTA improves on the convenience from its predecessor with its super easy air mode switching capabilities. The unit comes with two different airflow inserts that have different slots that give you more variety in the airflow. The inserts are designed to sit firmly on the deck with a simple push-pull switch. If you ever want to switch the airflow mode, you no longer need to remove the coils and go through a lengthy process - simply pull to switch from one to the other. The honeycomb dot airflow insert is perfect for a soft and smooth airflow, but you can switch it up with the slim groove in a matter of seconds to get a more vigorous and intense airflow through the RTA. After the air enters the bottom inlets, it is immediately metabolized by the air balancing structure within the Troll X RTA. Easily adjust the airflow in the Troll X RTA through its flexible air control air balancing system to enjoy a smooth and controllable air supply through the unit for an enhanced vaping experience. The easy refill design lets you refill your tank without creating a mess. Simply push open the top cap, refill the flavor, and pop it back on to enjoy an uninterrupted vaping experience on the go.
