The Oumier Gragas is a rebuildable dripping tank atomizer. The device is easily transformed from an RTA to an RDA by removing the tank section. If used as an RTA, the tank has 4ml capacity and it is leak proof. To add e-juice, you can just use the easy top fill system by removing the top cap and squirting juice through the fill hole. At the bottom, there is a 510 connection to ensure that the RDTA is compatible with most mods.
The extraordinary feature is the free refueling system. You can just press the top cap to push e-liquid from the tank into the bottom deck. In this way, you get an RDA vape in a tank system. The build deck features a dual SS / brass post setup, which is suitable for large and intricate coil building.
Airflow is also versatile with 3 airflow slots located between the deck and upper tank, which can be configured to a wide range of settings. It is a perfect tank for you!
