I just bought a nautilus mini about a week ago. I had some issues in the beginning with flavor and getting it primed, that has been sorted out and the flavor is great now. The Vapor is great when it wants to work properly, some times I get big clouds sometimes it barely produces any vapor. Has anyone else had this issue? Am I doing something wrong? It is not leaking or gurgling. I have adjusted the airflow. Not sure that is going on, about ready to give up and try something else.
