Improving on the original Smok VCT, the new Smok VCT Pro has numerous updates to the tank itself and Smok's proprietary coils. The tank comes with 0.2- and 0.6-ohm coils, which now have rectangular e-liquid intake holes that allow it to work perfectly with thicker, VG-based juices. The U.S.-made vertical dual coils have organic cotton and Kanthal wire that takes advantage of the Smok's improved adjustable airflow system that has wider air slots compared to the original. The tank also now comes with a glass drip tip with an adjustable heating fan for easier and better airflow control and reduced heat. The slim design Pyrex glass has a 5ml capacity. The VCT Pro is also backwards compatible with the Smok TCT (temperature control) coils.
