Correct but it is recessed slightly like the Ego is to a 510....Its a great Connection...It resembles the slightly more airy draw of a 808/901 compared to 510/306 type of hit.
That's exactly what it was...With a little frustration added in, I think. I received a very humble and apologetic email this morning, which was humbly accepted...He received an EGo instead of the Mini Nova, which I actually prefer (when they can be used without a cone) so I think it might have been an unintentional thumbs up either way.
Thank you Drew!!Here is the video that I posted today that further explains filling and simple fixes for airflow issues.
