Aspire is the first to implement coils that remove the need for a chimney within the tank. The Cleito revolutionary new coil design frees up the airflow by removing the chimney within the tank. This results in direct airflow, which helps greatly boost flavor profiles and create even more vapor than usual. This version of the Cleito Replacement Coils are specifically designed to be used with the Cleito Exo. The Aspire EXO replacement coils are coils that were crafted specifically for use with the Cleito EXO. These coils have been enlarged and provided elongated wicking inlets for use at higher wattage. Due to the enlarged sized of these coils, the 0.16 EXO coils change the Cleito EXO tank to a 2.0mL tank.
