I've heard that mediocre factory QC means that some of the HOG regs are fine regs, and some are not so good. That was from a tech instructor who doesn't sell gear, but based on what they had seen.
You heard right. In my experience, Hogs are big old POSs. I would never use them again if they were free. Multiple issues on multiple regs all due to poor QC. It irks me how many people love them, because I'm sure there's good ones, but there's way more cramp ones than their should be. I think many have had good experiences and others are happy with their regs eventhough they're not awesome because they bought them so cheap.
