Alligator Clips Electrical, 20PCS Preminum Test Leads with Crocodile Clips, 5 Colors Jumper Wires Kit with Testing Probes for Electrical Testing with Dual Ended Insulators for Circuit Connection

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.

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.

So many and so inexpensive! Great for science club and classroom! Functional and delivered on time!

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.

Not the best japanese jumpers I have ever owned. Plastic shield slips and makes it very hard to open the claw.

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

Premium? I would hate to see economy. I was excited when these arrived. They looked good in the pack. I opened the pack and a red alligator clip just falls out on the desk. Well hopefully they sent me a spare, nope just a red jumper with only one end. Oh well for the price I can live. I thought anyway, i used another set to attempt, attempt being the key word, to power a radio. The radio would not power on. It had just came in so I thought the radio was toast. Nope the jumpers were bad. Both of them. I would be embarrassed to sell these.

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.
