30PCS Premium Alligator Clips Electrical, 5 Colors Test Leads Cable with Crocodile Clips, Dual Ended Jumper Wires with Power Test Probe for Electric Welding Testing Experiments, Circuit Connection

The Beats having to make my own which I've done in the past. You can't beat the price for 10 of these excellent product for testing electrical issues.

Good very good on everything good clips

Handy low voltage jumpers for projects. Seem to be well made and reliable. I can use them as jumpers or for my test equipment. Small and light and no raw edges for shorting should they touch the board.

Leads have thick insulation but thin wire.Jumpers average .7 ohms resistance.High for short jumper, wires are crimped not soldered at ends.My tests show that it's the wire itself causing the high resistance.They will however do for low current use.Clips are decent quality and could be reused for other purposes.

I've only been using these for a few days but so far they have done great. The rubber boots are just a little too slippery on the inside for my tastes as it lets the alligator clip slide out of the rubber like a well stuffed hamburger out of a bun when you bite into it, but I can forgive that given that they are the cheapest usable test leads I could find on Amazon. For the few times a year I actually need test leads like this, they will do just fine, I've already finished the project I bought them for.

OK - But not that good quality , 4 out of 10 did not work right. but OK for the money I guess.

Never seem to have enough of these if you're a DYI person or you just need to extend a connection briefly.These are pretty decent for the money. The wires at least a foot or more, (more). The alligator clips are a real strong point, depends how you look at it. The springs in these gators are rigid, very rigid. I can't even recall when I've had any alligator clips that have this much tension & thus grip.Obviously these Jumpers are not for use with anything that pulls any real current, so if your planning anything more significant, buy a higher gauge jumper set.I tested all the sets for continuity and they all passed. I only mention that as the wire to clip is only clamped, not soldered, i'll probably hit them with solder per job, if im soldering @ the time. I'm not sure about the plastic boots yet, except they do what they should, stop an accidental short to something close to you're work area. That's good, but the springs are so strong and the boots, so slick, it's difficult to pinch to attach without pulling back the boot, then putting it back. A Small pair of needle nose pliers is advised, but not needed. Once the clips on, it's got plenty of grip, they'll most likely be as difficult to remove as to attach. (Needle nose) pliers or any small pliers work and makes set up & break down, effortless.Definitely recommend these for light jump & testing. They do what there designed to do, and if you do Over Amp them, there cheap enough to discard & replace. Keep the gator clips if you do melt the wires, they'll make great accessories for small soldering project. I'm surprised McGyver didn't have these in his pocket with the Swiss army knife & the duct tape. I'm just say'in...saying....Blackroadster1

Zero Stars Would Be Generous — These Are Nice Looking, but electrically useless.These jumpers set a new low bar. Bought these for quick continuity checks on a benchtop setup, and after chasing my own tail for way too long assuming my circuit was the problem, I finally put a meter straight across the alligator clips themselves.Infinite resistance. Clip to clip, on a brand new lead, straight out of the package.Looked closer to see what was going on, and the "manufacturing" is exactly what you'd expect from a cheap bag of these: the wire insulation isn't stripped before the crimp goes on. The crimp is just squeezing down on the jacket, never actually touching bare copper. So the clip on one end has zero electrical path to the clip on the other end — it's not a jumper wire, it's a decoration shaped like a jumper wire.The infuriating part is these look fine. Clips work smoothly, wire gauge feels right, connectors seem sturdy. There's no visual red flag — you will not catch this without a meter, and you WILL burn an hour troubleshooting your actual project before you think to suspect the jumper itself.If you buy these: test every single lead with a multimeter before you trust them for anything. Don't assume "new equals working." I'd guess this is an inconsistent QC issue on their crimping line rather than every unit being bad, but I got a dud straight out of the bag, and that's one dud too many for something whose entire job is to make an electrical connection.Save yourself the diagnostic headache — spend a few more dollars on jumpers from a brand that actually strips the wire before crimping.

Good alligator clips, large size.I had clips in the past and needed more. Very delighted as those ones are bigger than my previous ones, I assume it is also more resistant if they are bigger.Good quantity for the price (i paid10.97 CAD), recommended.
