Review on 🔊 50ft. Spool of UL/cUL Class 2 In-Wall Jacketed Pure Copper Speaker Wire – 18AWG Low Voltage LED Cable with 4 Conductor by Joshua Douglas

I only discovered the problem with this cable when I cut it to length to make the speaker select switch lead wires. Approximately 20 feet on a reel, the green insulated wire was BLACK, not copper. I could scrape the black stuff off the wire. He was solid. After finding the black wire, I cut off the rest of the wire in various places. I found at least 5 feet of green wire was black. Black indicates a bad wire. There is no way to tell if there are other segments on the same cable, or even other cables that have the same problem. I wasted about 2 hours of my time because now I have to order more wire and start over. Based on what I found I don't trust the quality of the ladder.
