WGGE 5PCS Dual Ended Alligator Clips Test Leads Set, 15A Test Lead Wire Cable with Insulators Clips, Heavy Duty Cable with Protective Jack Copper Clamps for Electrical Testing 5 Colors 3.3 ft/1m

Unlike most test leads and jumper wires, these are twice as thick and the clamps are super strong.

While I havent tried them at their rated capacity they are very well made and of very low resistance. The jaws open wide enough for most purposes though you do have to be aware of the possibility of shorting to adjacent components as the plastic shroud does not extend all the way to the tip of the jaw.

I have several different sets of alligator test leads already, but all of them are for low-voltage, low-current circuits. When I have tried to push them into higher-power applications, they invariably heat up and are unsuitable.

Nice to have for extra length to the leads on a tester. They are strong and flexible. The clamps hold tight. They are nice to have .

I like to use these when testing audio equipment. They allow you to quickly get power to a device with no cutting or stripping of wires. I also like that they are all different colors - very easy to trace from source to destination.

These alligator clip test wires are well made. The material used is nice quality and very pliable. The alligator clips are strong and hold well. These are very handy for all types of 12 volt setups. Highly recommend!

Having spent 25 years repairing electronics professionally, I have a large selection of test leads in different sizes for different uses. For higher current needs, these are some of the nicest test leads I’ve seen. The newer soft PVC insulation coupled with the copper wire design make the wire extremely pliable and easy to work with. The copper wire is what years ago was called ‘soft-flex,’ a very high strand count of very thin strands of soft copper wire. The alligator clips are non-magnetic with the exception of the spring and pivot pin. Scratching some of the plating off reveals the copper core. The springs are strong and the clip insulation is well designed to reduce the chance of it “snapping” out of the fingers while in the process of being attached.

The leads seem decently built. For automotive use I would prefer a little thicker wire being used. The leads are rated at 15amps. Of which customer states. If used diagnosing a higher load in vehicle (20-30amps). Such as a headlight, Radiator fan or heater fan circuit. The leads may be subject to a overload/melting condition. But, for general low load use they should be fine. There is a warranty on leads. But , most likely not allowing for melting for accidental overload. Pricing is decent so most will just buy another set if need arises. I would suggest a revision to listing. Stating what voltage leads can handle 15amps at(Most likely 12volts). Otherwise listing may make some assume leads can handle 15 amps all the way up to 1500volts listing mentions. I would consider leads a disposable item to buy. Not saying they are bad. But due to low cost and most damage/issues is most likely from improper use or accidental damage. The leads work as designed, Just use caution on use.

For the occasional project use, these should be ideal. The ends are fairly insulated as far as fingers, but leave aa fair amount of clip exposed so they cant really be used in close quarters with each other. The springs are pretty strong and the teeth on the clips are fairly sharp.

I love these. I will use them from jumping thermostat terminals, to connecting power sources to devices. Can even use them to hold wires in place that are to be soldered. The alligator clips have strong springs and they open wide, as shown in my pictures. They are well insulated so there is no issue of two of them touching each other making a short. The wire is long and very supple. They can handle up t o15 amps, but I wont be testing that much current :-)
