This business of buying stuff from “greater Wuhan” in general, is a worry.
I just had a root through my tubs today, looking for the DVI <==> HDMI lead. I found them!
I found however, a bag of (?50) of the coaxial power line sockets that fit (for example) the “barrel connector” of the Arduino Duemilanove/ UNO etc. I noticed many of the latticed strain reliefs had broken off. By squeezing the bag, I can easily crush the whole of the cover of all the connectors, just like popping bubble wrap!
I might as well just for fun. After all, they are - at least the covers - completely useless in this condition. If it is non-critical (or even if it is?) I can just bodge up the connectors with heatshrink as a cover, perhaps two layers and that will be as good as the original covers, it’s just the appearance of it (and the extra trouble).
And another bag of a smaller quantity is just fine, the plastic is flexible. It was obviously a dud batch. Is that why they sold them “cheap”? They were apparently intact when I purchased them a few years ago but they have completely failed and thus were absolutely not “fit for purpose”.
This did lead to some household discussion about the consequences of our total dependence on that country even aside from that business about the 5G company.
