Thanks George I was told to add about 5 drops down the center of the coil to prime it (now I will let soak also ) Ive been using it for about 2 days now The flavor/cloud is a bit better (to me) then the KPT2. But the one thing I like about it the airflow control to me its a lot more user friendly than the one on the KPT2 Im also using it with a 70vg mix that could be why the flavor/cloud a bit better?
