I'm tempted by that supposedly flavor-centric airflow and leak resistance, but it's tall and looks like the
juice well is small.
Appearances are deceiving. The overall length is 34mm, so it's about 5-7mm taller than a conventional RDA, but... the inner cap and smaller build deck/
juice well reduces the chamber net volume considerably... which improves both flavor and vapor warmth, while the net air flow maximum is actually on par with more common, high-flow direct alignment RDAs.
The outer sleeve and cap are part anti-drip baffle, part inlet air flow pathway and part straight wall, 22mm OD styling element. The "Dual thermal-protective casing caps" function to direct cool, inlet air flow between the inner and outer outer caps, keeping metal temps nicely cool.
You can actually vape it with just the inner cap in place (it functions more like a small chamber, conventional atty this way)... and just like any single wall RDA, it gets pretty warm with a low resistance build.
You can, depending on your aesthetic (along with tools & ability), taper and radius the outer sleeve and cap... so it looks less like a hunk of 22mm SS bar stock, and more like a "normal" RDA. ;-)
