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

They are great for making Arduino breadboards. I haven't had any problems in this area. My problem arose when I was making a small PCB, I cut some wires to solder one end and left a socket or plug on the other side. Some wires cannot handle solder. I peel off the plastic and see the black coating on the wire - no matter how much flux I use these wires won't solder and it's a huge pain. A little more quality in the wire would have helped. Not all wires are like this, I've found this often happens with white wires in my batch. UPDATE: Elegoo contacted me and ended up swapping the wires. Haven't had time to check if they have the same soldering issue but I've upped the rating by one star as Elegoo seems to genuinely care about their customers. As soon as I get a chance to solder one of these (there should be one end with a connector here and I'm soldering the other end) I'll update the review again. Either way - great customer service - thanks Elegoo!
