The 0.4Ω pod includes COREX 2.0, an improved version of the first generation with precise adjustments to the morph mesh grid size for superior temperature compatibility, resulting in quicker heating and a flavorful vapor. Upgraded cotton effectively provides e-liquid, preventing any burnt taste and prolonging the lifespan. These findings have been verified by VAPORESSO LAB test results. In the US market, the kit comes with 0.6/0.8Ω pods, while the 0.4Ω pods are currently unavailable.
