Review: No problems with the product itself. The pins are so small they're difficult to work with without a specialized tool, but I feel like there were plenty of pins for my needs. I needed this to make an extension cable for my Vevor diesel heater controller and it was the exact size I needed. I took a gamble and it paid off. I will just say, however, that there are actually only 3 wires needed for it and these connectors allow for up to 4 wires, so if you're using it for you diesel heater or something else be careful to wire up the pins/connectors correctly so it aligns with the stock male/female connectors in the diesel heater or other device(s) you're connecting them to. That should go without saying, but I figured I'd mention it just in case someone hadn't already considered that themselves.
Review: I bought these to make an extension of the wire for my Bambulabs AMS Lite. They worked fine.
