Elegoo 120pcs Multicolored Dupont Wire 40pin...
I selected a couple of wires at random and measured approx 0.25 ohms which is quite respectable.
I have ordered a number of different items from Elegoo and all have been high quality. I would not hesitate to order anything from them in the future.
- 2 stars: Chemical odor of the plasticizer used in the vinyl insulation apparent immediately upon opening. This is common for inexpensive wire from Asia. I put them in the garage to air out, and I can definitely smell them in the closed garage. Hopefully the odor will fade.
Update: I baked these out in the oven at 170F for 3 hours and most of the odor is gone from the wires. (after airing out the house too!) Elegoo said that this was "normal plastic order and does no harm to the human body" and offered to send another set with "no odor from China". While I appreciate the offer, I don't have the time or inclination to wait for another set, so I will make these do. Note: many PVC compounds are banned from children's toys in Europe because of the suspected toxicity of the aromatic compounds in the plasticizers. Don't eat these wires.
I did find the plastic smell when I opened the shrink wrapped package very strong but once open for a little while, that cleared up.
Seller has replaced and so far I haven't run into any more defects! Problem on old batch seems to be in the crimping of the connectors. That defect aside, they are as-advertised and really helpful in testing.
A considerable number of the wires of at least the M-to-M and F-to-F sets (haven't used the M-to-F) are defective and not actually connected. I imagine most had better luck, but just be aware that there are some bad units out there.
