I gather that the USA company can come up with a good design and send it to their Chinese factory to build it. Not sure who sets quality control on components initially. Then it comes back to the USA for testing to see if it meets the specs. Then it goes to market.
Then they wait for failures and get a notion of what keeps breaking and change that component if too often. Might even have to redesign some of it. Eventually it gets better than original.
With the market competition being so tight, nobody can afford to have higher costs and go broke, so money margins are very thin.
So I can see how these things can happen and that's fine. It is amazing in a way that so much of this fairly inexpensive stuff works as well as it does for as long as it does.
(I disagree with Mex in that other thread about the good old days. It is silly to fix something when it is cheaper to replace it, and how much down time was there while the guy in the shop fashioned a part from scratch and how much did that down time cost etc etc)
Things are therefore made with fine tolerance margins, so if a starting procedure makes a difference in how long it lasts, then it could be worth knowing that.
