You can buy jumper wires from thousands of places but these premium jumper wires are premium quality. I don't give them much thought on a breadboard or Rasberry but for use between components on a $20,000 drone carrying another $12,000 in camera equipment and working for a client your charging a lot of money for your services, it not something you can just give a wiggle if you don't have or maintain a good connection. That's when you really appreciate the use of good wire that's well insulated and that has been mated to a sturdy connector with a quality spring to keep a firm contact with the pin that you know won't vibrate off or have the wire separate from the connector and not giving off or picking up noise in systems that depend on RF to stay in the air and broadcast clean video back to the ground. It's nice when you find a basic, generally minor component that someone still takes the time to put together with some pride rather than trying to make it as cheap as possible. I'll fill my flight box up with these.
