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.

I bought these to make an extension of the wire for my Bambulabs AMS Lite. They worked fine.

Worked just the same as other connector once I had crimping tool to finish the job.

I ordered these to make inexpensive 4-wire test cables for use with resistive temperature detectors, and I chose 24 AWG cables for good flexibility. I had some trouble with other connectors that were listed as suitable for 24 AWG wire, and I can usually get good results with crimped connectors, even if I'm not an expert. I chose these Micro-Fit connectors because they're a little smaller but still fine for my low-current application, and I immediately got good and consistent results. My first crimps were good, all 8 of 8, enough to complete two connectors so I could test them. The connections seemed mechanically sound and the wires felt firmly crimped in place. Electrically, the two mated connectors added roughly 4 milliOhms to the resistance of each circuit, and they all measured within 1 milliOhm of each other, which I found reassuring. These initial sample results are well within the Micro-Fit connector specs that I've found online and are certainly good enough for my purposes, so I'm comfortable thinking they will be quite robust.
