I was in a hurry and didn't read the reviews. How tricky can a simple crimp connector be? Well the box was broken for starters! Everything looked fine until I removed the shrink wrap; Two attachment points were broken, meaning the lid won't hold up. And the connections are of the same quality; The rings are very small, forget about connecting with a decent screw. The metal will be crimped unevenly, one side will fail and the other will not hold the wire. The wire pulls out easily. In summary, this set is a cheap Chinese carp.!
