They seemed like a great deal but when I used them I found that most of them were unreliable or defective. Most connectors are too loose and don't make a good connection, I had to throw away a ton before I found any good ones. There may also be internal issues with some wires. I ran continuity tests and some of them failed. After all, they took me a lot of time to fix bugs. Spend more and get better quality.
