Got a few as a freebie. I use silivon wires from it. Also the plugs turned out nice to use because they are so universal. The sermo connectors come apart form each other and can be easily clicked together in a row or in a scuare pattern. For example 4 plugs in a row! Or 8 plugs for a multicopter esc-s. Quite interesting solution like LEGO bricks. There is no male or female - all is the same and they connect-pull apart so easy. Looks like can handle big amp draw too.
