Review on 🔌 ELEGOO 120pcs Multicolored Dupont Wire Kit: Male to Female, Male to Male, Female to Female Jumper Wires for Arduino Projects by Josh Allred

At this point, exactly half of the wires used actually worked. Six out of twelve. The rest had no conductivity. Endless Resistance. I removed the insulated end caps from one of the dead wires and found that the connector had been crimped over the insulation. It definitely won't work. I spent about twenty minutes debugging the breadboard circuit before deciding to test continuity on something as simple as a wire. My mistake is that I assumed they would work without prior testing. I think I can give three stars as half of them seem to work, but only two as they wasted my time and money. Look elsewhere when you need truly reliable conductors.
