Greater than one weekI bought these to solder to my arduino for a project that I am working on. I have not yet used them, but they are made of good material (solid) and look forward to using them soon.

11-06-2025The pins are good. I didnt consider pin construction when I bought these. These square pins do not fit the round pin female headers that I bought. It is not worth the time and expense to return these, I will most likely buy square female headers for future projects. I have already bought round pin male headers to mate with the round pin female headers. Make sure you specify round or square pin header when you search for pins.
