hey guys hope you’re all having a wonderful weekend!! So just recently bought the Manta and I love it. Great build quality love the 5ml tank and the flavor and vapor production are both amazing. I’ve noticed sometimes when I fill it up it will leak a bit and stop. I have now made sure to not fill it completely and I close the airflow when I fill it. Should you be closing the airflow or no? Also is it necessary to leave a bit of room for air before screwing the top cap back on ? Any feedback would be greatly appreciated. Thanks and vape on
