I like the shorter lengths when working with led segments and these work well for that purpose.
I am working with 2.5" led segments.
These will work with any electronics project where you have to tie pins together.
Good for quick wiring pins.
But there were plenty good ones for my project .
5 wires were missing the plastic connectors, so far out of the 5 wires I've used 4 of them have pulled out of the terminal by simply connected it to a header.
I suggested finding an alternative.
Sloppy fit, impossible to get a reliable connection.
Doesn't connect well with pins, tends to slide off .
