If you got through the Ultra Sonic USONICIG Rhythm's pod and are looking for a new one, congratulations. You are one of a few vapers in this world that have experienced coil-less Ultra Sonic, a technology never before used in vaping.

Each pod holds 2mL of e-liquid and has ceramic plates that vibrate 2.4 million times a second. No resistance - just MHz.

This is a top-fill pod, and refillable - good for 5000 hits. An interesting airflow system means you have cross airflow. Vapor leaves the evaporation chamber, and makes a detour into the side before coming back up to you. 

Your replacement pods for the Rhythm are made of Delrin and sold individually. Requires the USONICIG Rhythm mod to operate.
