Review: Works as expected - I made a custom laptop stand using computer case fans with molex connections and needed a "sacrificial" molex cable to cut up and splice onto an on/off switch. Since I'm only powering case fans, it only needed two of the four wires, so I pulled out the two I didn't need (which is why there are only two wires in the my attached pictures), and soldered it all up. My previous molex cable was loose so the male end would just fall out if you breathed on it. The female end of this molex cable holds onto the male connector properly. I mean, there's not much to say - it's a molex cable and it delivers power.
Review: Good product. - Works like it should.

### ⭐⭐⭐⭐⭐ Good product.
*by W***T on October 20, 2024*

Works like it should.

### ⭐⭐⭐⭐ Fine cable, finicky pins
*by S***Y on March 19, 2025*

It's a molex cable. Works fine! What more could you want? Well, one complaint is that the pins inside the plastic connector housing wobble around a bit, since they're crimped to the wires and the plastic housing is sort of just slipped onto them. This is electrically and mechanically a very sound way of making such a cable (better than injection molding the whole thing), but it does mean its sometimes difficult to plug the cable in because the pins keep shifting out of alignment as you grab the cable.
