You can use a dry cloth for exterior cleaning and a dry cotton swab to clean the contacts inside the STLTH LOOP 2 Device.
Please check for debris in your charging port if your device isn’t charging properly. You can remove the debris from the charging port and your issue should subside.
We recommend cleaning your LOOP 2 Device’s airflow control located on the bottom of the device (Airflow Slider). These holes are responsible for the airflow. One of the major reasons why could be experiencing a tighter hit or no vapour could be these holes are clogged.
