I am really attached to these cute little buggers. I do find the clips a touch difficult to open, but then, my finger strength isn't as strong as it used to be. They are a nice length and do hang on to whatever you clip them to. So if you too want your very own "family" of alligators... get em today!

They work as testing, jumping circuit. The silicone sometimes makes it difficult to squeeze to open clamps.

Description is false making this an unsafe product. Lists as 18awg, but is closer to 24awg. See picture comparing to a true 18awg wire. It is not even close. Also a big issue is there is not evidence the wire makes a proper connection to the connector. It appears to just be wrapped under the insulation and pressed against the connector. That also makes it unsafe.

These jumpers are perfect for everyday use. These are great for troubleshooting and field service. Overall quality is fair, but given the price point that is exactly what I expected. Overall These are good for non-critical testing, mock-ups, and testing on low current demand applications.

I have used similar jumper cables in various projects but needed something that would take 2 to 3 amps. These "18 AWG" jumper cables looked to be ideal for my needs. 18 AWG stranded cable should be able to comfortably handle up to 4A.I was surprised at how bad these cables were from Groupchn. My first application was to use them to deliver 2A at 5V to a breadboard circuit - there's nothing very demanding here. However, the circuit wouldn't work at all! Finally, I found that the voltage applied to it was just 2.5V - half the voltage had been lost in these jumper cables. Further measurements indicated that the electrical resistance of each of these cables was just over 0.6 ohms. This meant that if I used 2 of these cables to make a connection, the total supply resistance would now be 1.2 ohms. Passing 2A through 1.2 ohms would result in a voltage loss of 2.4V!!! This is criminal! It should also be noted that this represents about a 5W loss in power within these cables which quickly get very warm even at 2A.The assembly is very poor, too. Bare wires at each end of each cable are simply folded back and loosely crimped to the crocodile clips against the thick silicone cable sheath. This will probably make a poor and erratic electrical connection.The only (slightly) positive thing about these cables is their low price. This is why I'm not sending them back - it looks to be fairly easy to remove the wires (I could probably just pull them out) and replace and solder them with some real 18 AWG cable I already have!

These are mostly quite good. However, the conductor in the wires is awfully thin so don't be expecting to push more than a a few Amps without things heating up. The covers are also a bit slippery and can sometimes just squeeze out between your fingers as you try to make a connection. Overall though, good value as test hookups.EDIT: Some time later I've found a few of the cables were not connected end to end. The reason is that the center wire is not soldered to the clip. The bare wire is folded back against the insulator plastic and crimped in place. In some cases the wire has worked loose from under the plastic. I've had to solder most of the ones I use regularly and now solder them routinely before use. It's very frustrating to be using them as test clips when they are open circuit.So beware. They are made cheaply.

I had searched for test leads that specifically has 18 awg wire because it is heavier and more robust than smaller gages. These test leads were listed as 18 awg, but in fact, they were smaller - perhaps 20 awg or 22 awg.

These test leads are low cost so not well made. Alligator clips are crimped on with bare conductor folded under insulated conductor and not soldered. 3 of the first 10 I tested did not conduct so I sent them back. When troubleshooting electrical problems, the last thing you need is intermittent test leads. If you want to order you could re-crimp and solder to make ok for use on very low current. Also when packing up to send back I noticed I had been sent 1 less lead in one of the 3 groups of 10.
