To meet the demands of both MTL (mouth to lung) and DTL (direct to lung) vapers, the kit is designed with two different airflow bases for the various coils - the sub-ohm base that is compatible with 0.2ohm M1 coil and 0.15ohm M3 coil, and the nic salt base that is compatible with 1.4ohm NX coil and 0.15ohm SX coil. The nic salt base comes with dual airflow adjustable slots to let you adjust the air by rotating the base. Utilizing the convenient top e-juice refill design, you can just press the triangle button to slide out and reveal the large filling hole, without leaking worry.
