GoupchnStackable Banana Plug to Breadboard Male Jumper Wires Soft Flexible Silicone Test Leads for Electrical Testing

I used these to feed power from a bench supply to a few breadboard projects without need for jacks, etc...As they are stackable--I also used with multimeter to measure circuit amps...very handy for this... I like them overall---but beware--make sure you understand that the leads are very short..ie..maybe 6-7 inches ...which means whatever you're plugging into needs to be very close to your project. other than that, nice silicone wire..sturdy dupont pins and banana plugs seem to fit well...would give stars if a couple of inches longer...lol

Great for getting power supply to a breadboard, and getting from a breadboard to a meter, etc.

The pictures do not convey just how thin these jumpers are. The banana plugs and the dupont pins are the cheapest, lowest quality available, and the wire reminds me of cat whiskers. The whole assembly feels relatively fragile. They’re very flexible, though, being silicone-insulated, and don’t retain their shape like other, springier jumpers, which is nice. They do exactly what they’re meant to do, despite their flimsy construction. If you’re looking for a quick, convenient solution for connecting banana jacks to breadboards, these do fine, but if you plan to use them often then you might do better just making some yourself. Get a thicker gauge silicone wire and sturdier connectors — for instance, dupont pins that fit tighter in the breadboard sockets and don’t have room to wiggle around so much.

Good collection of jumper cables. Even though the picture shows all colors in pairs mine was not. Three red and one black jumper wires

Just plain okay. The leads are shorter than what is really useful. Small gauge wire can be stressed easily. Mostly okay, if you are just connecting a multimeter to a breadboard.

Aliexpress garbage. The banana plugs bend easily and the spring leafs on them are weak, the lead is 26AWG or 28AWG, even thinner than the regular Dupont cables you normally breadboard with, and the Dupont connector is loose and won't fit tight in any breadboard I own. I wasted five bucks on these. They aren't even saleable.

These are great for connecting pluggable items into a normal breadboard, or anything you need to plug a small pin into. I've been able to connect into several tools around the shop and wire in to smaller proto systems without having to resort to gripper clips that are prone to slipping.
