The Crystal 2 has an adjustable airflow atomizer that produces only true vapor. High levels of heat are required to vaporize the material in the chamber, and by restricting airflow the vapor that is produced and inhaled will be less diluted by incoming air. This airflow is adjustable, and if you find that your atomizer is getting too hot your your personal use we recommend using one of the two lower voltage settings, opening the airflow, and allowing a few minutes for the device to cool down between uses.
