MCIGICM 10pcs Male Header Pin, 40 Pin Header Strip (2.54 mm) for Arduino Connector

-I agree with the other reviewer re: solderability. I could barely get my aggressively fluxed solder to stick until I cleaned the solder end thoroughly first. I used 99% rubbing alcohol, wiped on and wiped dry, twice just to make sure. Solder problem solved. -They dont break apart as precisely as some of the others by hand, using needle nose pliers helps a lot.

Doubt I got a single 40 pin strip, they all came broken into various lengths already. Not that I need anything that long, but would have been nice to have full 40 pin sets to start with before breaking as I need.
