Review on AUSTOR Double Prototype Connector: Efficient and Reliable Solution for Enhanced Connectivity by Eric Mueller

Having used every single part in this kit - screw terminals, jumpers, female, straight and 90 degree connectors and of course breadboards - I have no complaints. I've screwed the wires into the screw terminals dozens of times and they still hold up. There is some tinkering to do with the breadboard's contact pads, as I soldered and soldered into the same pad with no problems. Note that the 22AWG stranded wire fits snugly but snugly in the breadboard holes. I wouldn't go any wider.
