Banana clips are high quality, I used 12 awg wires and had no issues. It secures into the plug with 2 small screws, you will need a flat terminal screw driver to install them. The quality was high and made a good connection. If I had to make one complaint it would be that I would tighten the gray piece to the plug and it always kept spinning, otherwise, excellent product.

Worked fine for me

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.
