So far those are good connectors. Used about 6 packs. The biggest problem is that they don't come with a sliding tool and the one I've found doesn't cut the wire close enough. As a result, the plastic caps don't snap into place like they should. The solution for me is duct tape, although that's not the way to go; This is my home. Otherwise I get strong signals over my network with no packet loss. Overall I am satisfied with the purchase. Just with them came a good sliding tool.
