Ive been using my trusty mutation x v3 for almost a year and a half and its the only rda I ever use. Ive also used the doge, magma, atlantis and kanger subtank. However Ive grown tired of always using the same thing but I cant find anything new that I like because Ive become so accustomed to the large airflow. A good place to start for a replacement is whatever rda has the largest airflow. More importantly though I would rather find a subtank because they are so much more convienient. So what Subtank has the largest possible airflow?
