China is no better than anyone, neither America.
Yes, the consumer sees as far as the given appliance and it's price.... and think they got a bargain. no.
What they have is a piece of of equipment that is not backed in it's component selection and build quality. One that does not have 20-30-40 years of experience behind it's execution/build. thus the lore and knowledge that it takes to make something that WILL last 20 years or more before failure, is not there. OR that it might blow up 2x-3x-4x times as often. This, as the time required to get to that lore level and knowledge level, is not there...yet. You can see this, if you look around ebay, for example.
99% of the folks who buy lets say, a DAC off of eBay have no freaking idea if the AC transformers have ever been tested for UL or CSA approval in appliances in Canada or the US or the UK/European Union.
The answer is that...none of that stuff meets code.
NONE. You'd have to have extensive experience in copper, and extensive experience in running the enamel coating hardware, extensive experience in designing the enamel coatings, extensive experience in using said enamels, extensive experience in pulling said finished wires over cores, and about another dozen areas of design and execution, just to make the power transformer..so that it does not burn houses down.
So when you look at these sorts of things... remember, some of them have no experience beyond slapping unknown parts together into a box, with unknown consequences, regarding reliability and liability.
As far as house insurance goes, if you put such things in your house - you are on your own.
