Headers for your breakout boards
Not sure what to say, they're headers. They do what they do, and break apart easily. Fast delivery.

Good supply of all the most common headers
It's a good assortment of headers, pins and sockets. This is for boards, not so much for cable-ends, though one could improvise a cable end connector with these. The only trouble with these is that for the female socket strips, cutting it down to size requires crushing and sanding away one of the sockets, but that's no fault of the product, it's just the way it works, and all similar products are the same way. They are cheap enough that I don't care, but I've seen people complain about it. I've used these in several projects and fixes, and they have performed wonderfully.

Using headers can accommodate future changes.
Used these to interface to an Arduino. Changes can be made in the future if needed to acommodate wiring changes with new header without having to modify the Arduino. I keep some empty pins on the header to secure extra grip force when header is inserted into Arduino sockets.

This kit of male and female PCB board pins have been great. I have used these pins in many different configurations and they always have worked well for me.

Female not breakaway
Female side does not breakaway cleanly as they are not pre-scored. You will lose a pin in the process. Scoring yourself helps, but not ideal. Male side works as intended.

The femal strips in this set don't have breakaway pins
The femal strips in this set don't have breakaway pins, so when you cut them down to the size you want, you lose a pin and you have to do some extra trimming for neatness. Otherwise a good set.

This is as advertised and looks good.
These work well with my various Arduino processors.

The header worked well in my electronic project. Fit together is adequate.
