Another interesting point is that there is multi-tier manufacturing in Asia.
Items manufactured for U.S., or Japanese, companies have much higher quality and quality controls than items for the domestic - read Asian - market.
This is pretty much true across the board on items - clothing, domestics, appliances, etc. Look for the brand/marque and ask if its at "export" level.
Japanese, Korean, American brands...all made better than domestic. Even if it is made in the same factory or workshop.

I have heard of some Chinese brands that are trying to emulate this quality level, but the consistent/reliable Q.C. is still a problem.

Good point. Supposedly, cheating is often regarded as acceptable in China, if you can get away with it.
