content: eBay and Alix are both primarily "greymarket" sources for electronics. Most sellers don't know anything about the parts they sell and don't (for example) cut open the wires in each batch to inspect quality. It is often very difficult to find a seller that tries to stand out with a different quality product, especially if all of the products look the same.What do you mean by "quality"? Length, conductor material, conductor thickness, connector strain strength, insulator material, UV resistance, crimp contact material, etc? How did the cheap ones fail you? Depending on what you want an alternative to 2.54 jumper cables might be better.

content: They're cheap, low quality cables and there's really no way to know whether you're getting the bad ones or the merely not good.Just buy lots.

content: Dont buy them, they are not connected inside.I even tryd to solder them, it wont work.Better buy the round cables not the square ones.The round ones only come in packages of many small and a few long cables.If anyone know where to buy the good round cables long only, i would like to know.

content: Quote from: maseryoda394 on July 07, 2020, 02:28:19 pmThe problem is that the sellers are just in the middle of the distribution chain and get what ever their supplier has - there is no guarantee that you will get the same product every time from a given seller. For what it's worth, I have bought a few "Dupont" sets and they were all OK - not great but worked.Better to make your own "Dupont" cables. A decent crimper isn't that expensive and you can make them to the exact length you need.

content: Quote from: Monkeh on July 07, 2020, 07:49:29 pmYeah, that's pretty funny.I don't know where the Dupont name came from but the "Dupont" Company doesn't make these things, probably never did. I think it comes from "Dupont" connectors which also were never made by them.

content: @masery: this isn't a tree comment forum, you need to quote who you are replying to.N.B. those guys are joking, these cables are called "Dupont" as a slang name, I don't think Dupont actually makes any.
