10pcs Premium Alligator Clips for Electrical DIY Test Leads with 5 Colors, Double-Ended Crocodile Clip Roach Clip Test Jumper Wire Connector for Connection, Spring Gator Clips for Circuit Board Power

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

These alligator clips worked great for our science experiments!

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.

These gator clips are meh they aren't connected to the wire very well I took them apart and stripped some of the insulation back and soldered them back together, also the wires are not very long they will work for some projects and prototyping but I am probably going to buy some more wire and make a few longer pairs also the stranded wire is fairly thin it probably mentions that in the specs I just wasn't paying attention. There are a bunch of reviews over half actually that mention the clips are hard to open without them slipping around in the covers I haven't had that problem the clips themselves are very strong a little extra time, wire and soldering and they will be great. Good price good delivery time.

Good size bundle Works well
