Looks like a cross between the Odis 16 and the Origen Little maybe with some OG Goon airflow tossed in, at least on one side (can't see the other side) unless there is not a ring inside the cap and it relies on the deck to block or open the airflow
It does - from looks, I'd compare to Origen Little 16, except that it's "one-sided".
Not enuf air for me. If it was 2-sided I might be interested - I'd run air wide open, and try both single and dual coils to see. That's what I do with my teensy atties... Nuppins are like 18mm, and I run duals in 'em...
As per the videos I watched, the ultem cap has 3 holes of the same diameter as the barrel's holes, as well as a wide slot 180 degrees on the other side of it, and the ultem cap rotates independently to for adjustment to the airflow.
Comments I saw shows the 3 holes for MTL and the wide slot for DTL. IIRC, the holes are somewhere betw 2.5mm-3mm dia each so this atty seems to have plenty of air if you want it...
I'd only run a single coil. Even in my Goon v1, I only run a single coil. No interest in dual coils for me.
