The Mutation V5 XL just got bigger and a hell lot better. Introducing a unique double thermal shield, this allows for heat to insulate and effectively to prevent the RDA from getting hot over long periods of time while vaping. Also new is a creative airflow system to fully optimize airflow volume and surface area over the coils. The inside thermal shield contains two wide slots that sit right in front of the coils and the positive terminal contains two more holes to cover your coils from the back, maximizing the amount of airflow to cater to flavor and cloud chasers alike. With this style of build post, the two terminal design automatically centers your coils to fully utilize the airflow. All of these features as well as a 9.5mm deep juice well makes vapers keep going back to Indulgence's atomizers for quality products and performance.
