We used a alot of it at my old job. They were cheap a$$es, so I assumed that was why they bought it. I personally never liked it. I probably ran through 30, .035" 44# spools in a year, and every spool welded differently. Always needed larger than normal changes in wire speed and voltage, compared to other wires I've run. That and for the first day or so, it never fed right. It would always rub the gun liner hard enough that you could feel it while welding, even w/ a new, properly sized liner. Led to all kinds of burnback frustrations. Pull off the tip and watch it feed, and as it came out of the lner, it would twist and curl, almost like the first few outer layers of wire were twisted somehow during the rolling process. If I recall, Hyundai wire is South Korean, but I may be mis-remembering that. All I know is that when they switched to some ESAB wire, I was much happier.
