I bought 4 of these to wire into my first patch panel on an amp rack, i didn't know exactly what i was doing but i figured it all out, i found these to be great! very straight forward to solder and a good firm click latch which is great, no problems at all, I bought some nuts and bolts separately to fix it to the patch panel which was fine, i am very impressed with it and will be buying more for my next amp rack!
