Worked fine for me
Size: 10 Pairs
I saw some reviews that mention difficulty in threading or fitting. They are tight, but they work fine. I had no issues installing the speaker wire and no issues with the set/crimping screws. I even had one fall out when I loosened it too much and, though it was challenging without my glasses, I did get it to thread back in with no problems. I have purchased other BluRigger products, like HDMI cables, and they are of great quality.
