I'm a retired general contractor.
Over the last ten years, we bought equipment, hundreds of thousands of dollars of it, from different manufacturers. Some made here, some in Taiwan, some in China, some in Korea, some in Brazil.
The equipment that came from overseas not only met our specs, it exceeded expectations in the majority of purchases.
The lower prices overseas frequently made the difference between "we can do this" and "no, it's too much."
That difference kept us going.
Chinese, Korean, Taiwanese and other foreign companies meet specs.
If those specs are low, the product is low end. If those specs are high, the product is high end.
If you have a product in your hand that doesn't do what it was advertised to do, the nationality of the factory has nothing to do with it. What matters is who wrote the specs.
And for that, you should look closer to home.
The rest is fear, arm waving and xenophobia.
Carry on.
