The description said these connectors were "industrial and scientific," but they could barely handle a basic home setup... As a result of my tests I determined that these connectors were a complete letdown. The connections were cumbersome to make, and the plastic was of poor quality. The only pro was that they were inexpensive. However, that also meant that they were cheap. Save yourself the trouble and opt for higher-quality connectors that can stand up to real industrial use..See full review
