I ordered these integrated connectors as well as T-connectors to make a low voltage modular wire harness for my lab testing. They worked great. I wasn't sure at first if the insulation knives would go through my wire, but after reading the instructions that said to use pliers to end the short it all made sense and worked great. I'm not sure if you should reuse them, but I made a few mistakes in my design initially and was able to unhook and successfully reuse them. So they are not disposable. I'll probably buy some more.
