I don't know.... they are probably fine... They seem flimsy and the colors are pretty dingy. I wondered if they might be used when I got them because they look dirty. But they've worked ok so far, and they are so short that they probably carry signal fine.
Not a big fan of the molded plastic connectors, but again, they seem fine for what they are.
