Based on clues I see in the two vids posted Friday by Kistler my hunch is that these might be produced by Banax. Nothing at all wrong with that, in my opinion. I have several Banax produced reels and have had zero issues. Moreover, I enjoy fishing with them. The brake dial does look more like Doyo, but the Kistler logo is screened on, not the recessed oval Doyo stick on. Once we see a schematic there may be more clues. Banax uses a second driveshaft bearing above the ARB on most reels above $100 and a gear side plate pinion bearing. I haven't seen that second driveshaft bearing on stateside Doyo relabeled reels, and only a few Doyo's have a quasi dual bearing supported pinion where it's standard for most Banax produced reels. Also the series 1 spool shown is more Banax-ish than Doyo-like. The series 2 spools look like neither and more like a Shimano Curado's. The braking system looks to be SVS infinity-ish. Interesting.
I'll give Kistler credit. At least they didn't invent a tale about inventing new reels. They're straight up about the sourcing.

As far as quality control goes with Korean reels: Is the suggestion that they're unable to produce in- tolerance parts consistently, or their engineering is subpar, or that they simply pass finished products that should've been rejected? That's possible on any assembly line. As a high-schooler in the 70's I worked in a machine shop where we could hold tolerances of 10ths of a thousandth of an inch all day long on machinery produced in the 60s. It seems unlikely that they can't do this today just because of their location. Seems silly to me to if that were to be suggested. Absurd actually.
Anyway, it's fun to have more options out there. The braking system is different than any of the stateside offerings seen from 13, Lews, ABU, Okuma, or Quantum. Maybe there's some goodness in it.
