Top Customer Reviews
You may have noticed other reviews commenting on the strong solvent smell of these wires. I ignored those reviews because, after all, they're just breadboard wires so how much could they smell? Obviously the reviewers were exaggerating and complaining about nothing, right?
Wrong; very wrong. The strength of the smell cannot be emphasized enough. These arrived today. I opened the package in our basement. I couldn't believe how strongly they smelled, so I went upstairs--thinking they might air out for a while and the smell would be gone. Fifteen minutes later, my wife--who had been upstairs the whole time--asked if I smelled gasoline. Our central air conditioning had spread the odor throughout the house! This isn't a minor, offensive smell. It is overpowering. I sealed them back up in several extra plastic bags and put them in a box outside, and we have been airing out the house with all the windows open for several hours now--so far to no avail. It is almost as if I poured a gallon of gasoline all over my downstairs workbench. I can't even go back in the basement.
I've bought thousands of electronic components over the years, including plenty from overseas, and have never experienced anything like this. I can only imagine that the reviewers who said the smell doesn't bother them must have been lucky and somehow got some that didn't smell. But these are going back to Amazon, immediately. I would strongly recommend against purchasing these and instead buying wires elsewhere or perhaps getting one of the breadboard kits available on Amazon which include wires, just for the wires.
Aside from the smell, there were two other problems. First, these are incredibly thin compared to other jumper wires I have; probably half the diameter of the standard (NOT premium) jumper wires I've bought from Sparkfun. Second, as I was putting these back in the bag one of the black plastic finger holds fell off the end of one of the wires. So they don't seem particularly durable, either.
I had problems using them with a brand new breadboard and finally used my DMM to check the jumpers themselves. Sure enough, they are 3000-5000 Ohms where a normal wire is less than much less than 1 Ohm. This is not a problem with only one jumper (it is almost ALL of them) but even if it were, I wouldn't want to test every single jumper before using them.
Amazon will not accept returns on this product.
I would strongly suggest anyone considering this item to find a better product.
There is some kind of chemical on them that really really really smells - kind of like creosote.
After you touch them your hands have the bad smell on them. Leaving them open to the air does not seem to help. Either it is a coating (oil or some kind of toxic smelling mold release chemical?), or the plastic itself is emitting this chemical. I'd sure like to know if it's toxic.
I am going to try washing them in some kind of alchohol/soap solution to see if I can fix this. It's foul!
This pack of 75 is made up of several different wire lengths, with the most numerous being the medium length 4 inch ones.
These are of the same high quality as the ones supplied with an inventors kit.
Have had no issues at all with these. Would definitely buy again!!
The ends are not soldered in any way to the wire itself. It's a simple crimp (and honestly not crimped very well). I've already pushed a few of the pins OUT of the little black piece by pressing too hard on them. Of the wires I dissected, half the time the crimp missed half of the strands in the wire. Not exactly great quality control. But what can I expect from such a cheap product?
Overall, they work (hence the 3 star rating), but they are not "professionally terminated" as other reviewers mentioned. I do not have 100% confidence in these when I mock something up on my breadboard. Next time I'll look for soldered connections or simply make my own with some heat shrink.
