nice, iam definitely interested in one, the aspire bdc doesnt do that well on the provari because you have to back it off to get any airflow. It moves around too much and can get leaky, I want a tank i can screw all the way down and have adjustable airflow if necessary. Those replacement heads seem pretty expensive at their cheapest $18?!?! I want to get something in the next month or so since my new provari and juices from nicoticket(steeping in the closet smelling yummy) set me back a lil in the vape budget category. Can you recommend any rings that would look nice?
