I just recieved District 5fves layercake. I threw away the squank pin. I only drip. I think the flavor is better then the Cosmonaut and the vapor the same. The airflow is more restricted which I like for flavor. Ive had no leaking issues and u can drip straight through the top like the Cosmonaut. Im in love with this rda. The Cosmonaut was discontinued. It was my favorite. Any thoughts on this rda?
