I'm new to carto tanks and just bought a cirrus tank to use with my Provari. I'm getting so frustrated because I've been trying to use it for the past two days. I swear I did everything right (obviously I didn't) but when I pull I'm not getting any airflow. I had to loosen the tank to where it was not on all the way and was actually unscrewing and got some vapor but very little. I've heard good things about carto tanks and that they produce lots of vapor and flavor, which is why I got one but so far I've had no luck. I REALLY want to figure this out so I can start vaping with my new carto tank, please help!
