20 PCS JST XH 2.54mm 2 3 4 5 Pin Connector, Male and Female Double Connector End with 200mm Extension Cable AWG 26

All of the connections seem solid for what they are, none of the crimp pins came out of the connectors when pulled with a little force. I like to play with electronics so having a variety of JST plug/harnesses around is handy when hooking up power supplies, amps, and many other home electronics that utilize separate board components.

I don't know how you are supposed to get really detailed on a review of a product like this. So, I'll just go off my observations and hopefully that'll help others make sure this is what they need, too. The wires are a little thicker than the original wires I was replacing - though that is likely a good thing. There's plenty of length so if I have to cut the leads apart to use each side separately for repairs, it's perfect. The connectors seem to be of good quality and have no obvious flaws. The pins are straight and seem sturdy enough for standard use. And the connections of the wires to the connectors feel secure and solid. Overall, I think this is a good batch of JST connector wires for either extending existing connections or for cutting apart and using as repair material.
