Have used them on a project so far, no faults and the bolt/nut seems to hold them in place well. I haven't subjected them to much plugging/unplugging, but got good contacts. The only minor gripe is that they aren't symmetrical in relation to the connector, which can confuse the case design if you don't notice it beforehand. The soldering points are far enough away from the connector so you don't have to worry about accidentally ruining solder drips or wire ends. I'll buy more if needed.
