I tested them on #18awg wire and heated the joint on low heat with a dual heat 1500w heat gun. I pretinned each wire first and inserted both into the connector. When heated the solder melted and mixed with the pretinned wires. The joint coverage of the solder looks to be about 9% which is good for these connectors. I then did a resistance test of the joint. With a current of 1 amps and measured the voltage drop at 0.869mV or 869uV. This give a resistance of 869uohms which is very good. I don't use these every where but when I need to they will work fine. I would definitely buy these again.
