The Nautilus X's Replacement Coil is Aspire's new U Tech Coil Technology, an innovative and highly effective method of airflow in which the airflow will enter via the upper airflow chamber, travel down the first coil's vertical structure then return up through the center of the other coil structure before exiting the drip tip. Paired with the specifically spaced coils, the result is one of the most flavor intense vape experiences available on the market today.
