Hi, another new member here! 2 months off analogs and loving this new vaping experience. I'm have an issue with my aspire bdc ets tank. From the get go it will vape awesome. After about 10-15 of vaping the drag starts to get tighter and tighter. I was wondering if I need to look at getting an airflow controller. Does anyone know if the kanger airflow controller will work on aspire tanks. Please let me know if anyone has has the same issue. From reading elsewhere I think it's a common issue.
