Is the conclusion : They are too cheap to be true, but still within the specifications of the manufacturer ?
Ah, dear me, it is a complex matter.
I get really pi$$ed off at how many of my domestic appliances become faulty with intermittent failure. Of course, that is not necessarily to do with microchips, though sometimes it is. ADSL modems and VoIP boxes failing - I really just want to install them and have them work for a reasonable lifetime - ten years or so is not too much to expect. Presently I am faced with repairing my PABX which is just short of 30 years old and has required repair before. Frankly I see no reason not to expect it to work for another 20 years; sure there are more modern systems out there now but why should I have to replace it? All I want to do is to dial up people and talk to them. (Voicemail is grossly offensive most of the time.)
Clearly a lot of the stuff we buy is third-grade. Even "big name" products are suspect sometimes. Quality electronics should last 50 years and like the PABX, much of the time the requirement does not change in that interval. Who actually needs an Internet toaster?
But we are not getting quality. Clearly, counterfeiting is all too real, but it covers a wide variety of practices, from outright rubbish to products which may well work better than the original. We just have to live with it, it seems. Far too many people on this earth to do otherwise. :astonished:
