Digiflavor introduces their Siren 2, a follow up to their original Siren GTA MTL Tank, now with a 22 or 24mm diameter and 9 airflow options for various airflow restrictions. The Siren 2 is a top fill system with two large fill ports that is capable of holding up to 2ml (22ml) or 4.5ml (24mm) of E-Liquid. The two post, single terminal build deck has side mounted flathead screws which secure coil leads alongside a raised build deck that is closer to the drip tip for more intense flavor. Airflow enters the Siren 2 via a single adjustable bottom airslot that has 9 airflow adjustment options (included are 5 tapered airslots at various mm) for perfect airflow restrictions. Included with the Siren 2 GTA MTL Tank is a 5mm bore SS 510 MTL drip tip, a spare glass tank section, colored o-rings, and two prebuilt coils. The Digiflavor Siren 2 Two Post 24mm GTA MTL Tank retains the original Genesis inspired characteristics and retains optimal flavor recreation, making this a great MTL style rebuildable tank atomizer.
