OCM - 3 Wire Retracteable Test Leads - 18 Gauge Electrical Copper Wire, Alligator Clips, Impact Resistant Case

Arrived with some of the wires tangled inside, so it took about 5-10 min to work at them gently and untangle. After that I was able to wind and unwind many times without any problem. You may want to remove the rivet that holds it together and install a bolt so you can access the inside if they ever get twisted again. I guess -1 star for that. For my application I don't need three wires, but I needed to make sure these really are 18 gauge. I removed the green wire, cut it open, and measured the copper with a very accurate caliper. The wires are indeed fully copper and are actually even thicker than 18 gauge, which is better in every way. +1 star for being a quality product that is exactly what they advertised. Maybe +1 more star for being even thicker than 18 gauge? To the person who gave a one-star rating after they tried to "give some power to a motorcycle battery" in an "18v environment" and found "overheating within just a couple seconds"... Seriously?? It's about Amps not voltage. A motorcycle battery is capable of delivering 300 Amps. Even 'dead', it would still be able to source or sink way more than the 4-8 Amps that an 18gauge wire can handle. Take a look at any legitimate car charger and you'll see that have wires that are way thicker than 18 gauge. Car chargers with 'thin' wires, like the ones that go from cigarette lighter to lighter, will limit the amount of current so they don't fry their wires. I'm guessing you connected two batteries directly together and overheated the wires immediately due to too much current. In any event, you obviously pumped more than 8 amps through the wire. Do some homework before giving a seller a one-star rating! These are perfect test leads for may uses, including automotive. Just be sure to keep in mind the current limit for 18 gauge wire. Diameter of the wire with insulation is .1" or 2.54mm without pressing down on the calipers (to avoid deforming the wire). Diameter of copper inside is about .05" or 1.27mm, making this more like a 16 gauge wire. Thickness of insulation would then be about .025" (.025+.05+.025=.1"). Final note... When I cut the wire open longitudinally and measured the thickness of the insulation, I found it to be .03", which would actually imply a wire diameter of .04" (.03+.04+.03=.1") so maybe it really is exactly 18 gauge and my caliper might have been showing higher due to the twisting I had to do to the wire in order to measure it. In any event, it's definitely at least 18 gauge as advertised. Good Luck!

Bought for boat toolbox

These retractable test leads are great value for the money spent ..they were larger than i expected , so it does not easily fit in my toolbox but is still so worth it in the amount of time and frustration i avoid by using these. the housing is not cheap plastic, seems pretty thick and sturdy, and this little tool makes it so much easier to do continuity checks and run down electrical issues. I only wish i had bought this thing sooner. One note, this is not an automatic rewind , you actually have to spin part of the housing to retract the wires in to the housing which is great because i dont have to worry about some retractable band breaking . About the only thing i have to do is tape the the plastic covering or sleeve that is over the alligator clips . if you are not careful, the plastic sleeve on the alligator clip slips off and you can cause a short or get false readings on your electrical equipment

FAST SHIPPING

Very nice, fast delivery

"The item received aligns precisely with the description provided. It’s exactly what was advertised — well packaged, functional, and met expectations."

Some complained of twisting, but I had no problem. Pull them out and wind them up. Simple.

One of the leads lost its clip after the first use, it was simple enough to re install and crimp again but still a nuisance. Otherwise a great product.

As described

Excelente

Mécanicien automobile, il a l'air fragile et déroulé et rouler très lentement si non les 3 câbles se mêlent

Having three test cables that are this long that I can put away nice and neat is fantastic great item definitely recommend for any automotive mechanic

Good product, as described
