When working with solderless breadboards such as the BB830, you can use any solid wire in sizes 21-26 AWG. In the past, I have used insulated wires that I have cut and stripped myself, or a similar but convenient product in pre-made form. Often they work very well, occasionally the wire bends when you try to insert it by hand.

These jumpers are a step up from stripped wires. On both ends of each patch wire is a black plastic "handle" tube that makes it easy to grasp and insert the wires into the breadboard. They will probably last longer than simple stripped wires.

If there is a downside compared to the pre-made wires, it is that the pre-made wires stay low to the breadboard (if chosen or made correctly), and these jumpers tend to be a bit too long to stay low. But then these jumpers excel in connecting a breadboard to an Arduino microcontroller, or another breadboard.

They are inexpensive. They make wiring a bit faster.

But they are not a toy. It's odd to have to rate these wires on how much "fun" they are, but I have to admit that breadboarding circuits and making them work is a lot of fun.
