Brian Q. ★★★★★ Oct 22, 2026

For a pack of 200, these single-row headers are solid—the 1A current rating is perfect for my basic Arduino shield connections, and the 2.54mm pitch made them snap right into my existing sockets without any wonky fits.

Steven ★★★★★ Oct 21, 2026

The 500V dielectric test rating gives me peace of mind for my power supply prototypes. Pins are straight and consistent across the entire pack of 200.

Abigail ★★★★★ Oct 19, 2026

I’ve used these for a few breadboard and perfboard projects now, and the pins snap cleanly without bending. The 1 amp rating is plenty for my sensor wiring, and all 200 came straight and tinned.
