120pcs 10cm Breadboard Jumper Wires Male to Male Multicolored Dupont Wire 3.9 inch 1pin-1pin 2.54mm Connector for DIY Arduino Raspberry PI 10 15 20 30 40 50 100cm Optional Ribbon Cables

Good quality construction: #30AWG copper wire crimped on both ends with a male pin that works well in a solderless breadboard. The strain relief is properly done and the wire crimp has no insulation inside of it. The 10cm wires come in at 35mOhms and the 70cm at 70mOhms.

The part that goes into your breadboard has to be at least 26 AWG. 28 AWG is THINNER than that. BUT, the PIN / head IS a solid 22 AWG. At first I thought that 28 AWG was the consistent wire diameter, and that WOULD be too thin to stay in a breadboard. But the PIN/HEAD is (by caliper measurement and comparing to a known 22 AWG wire) a solid 22 AWG. And that is PERFECT for most all breadboards. So if you have a loose connection (as I did :( ), check your breadboard socket, NOT the wire being too thin.

These are the best jumpers that I have seen. The connections are soldered and very reliable. I tested one at one amp and it measures 55 milli ohm (.055 ohm) and doesn't get warm. I like these.

I definitely appreciated the price of these but they're also not the best parts in my experience. They'll usually work but I've had a surprising number of the tips break off the male jumpers. Maybe I had just spoiled by old RadioShack jumper wires though and this is standard. They're not bad, just maybe order a few more than you need to be safe!

Of all the many places to order these, this is now my top choice. Great price. My choice was initially guided by this seller's option for exactly what I wanted (a multi-pack of ~8" male-to-male jumpers) and not an assortment of things I don't need. The jumpers came inside a perfect-fit electro-static-proof-looking bag inside a box, with the jumpers perfectly flat and unbent (unlike many other sources that bend the jumpers in half to fit and then they always have they shape to some degree). It was the top-notch packaging, that speaks of the overall quality, that prompted me to leave a review. tada!

I used these to make little wiring harnesses for electronic projects I was building. It was easy to peel off just the number of wires that I wanted, and the wires and connections work well. I like having the different wires in a harness having different colors so I can keep track of what's connected to what.

I got these to make 14 wire cables. That was okay, but the wires separated from each other VERY easily.

Perfect for arduino and have held up well. Very durable and good fit for breadboards. Have 2 sets and will get more if I need them.
