Confirmed airflow sizes are 1.5mm MTL and 3.5mm RDL. There is also an extended tank for this RTA as well as 1, 1.2, 1.8, 2, 2.5, and 3mm airflow pins. I might possibly do a follow-up video / stream later when I can get them.
Otherwise this JIIIS ( J3S ) RTA as I said, is kinda just rad sauce. All the fit and finish is stellar, the deck is tricky to wick I’m not going to lie. The re-wick after this video on the MTL did get actually leaky on me. Like leak out the airflow leaky. It takes some practice IMO to really nail it down consistently. Flavor nation Utah though.
