After 50 years buying, selling,installing and repairing high-end systems… and watching the rise and fall of the chinese electronics manufacturing industry, I’d say that about 30% of chinese designed and manufactured products are at or above average quality and safety… often a direct copy of other products.
In real terms, a large part of the better products they make are designed and quality specified by overseas manufacturers… china provides a competent factory.
About 10-20% of other country products are built down to a price - and if you go there, at least it’s probably safe because of the origin country electrical or consumer warranty laws.
The remaining top-end products are generally pretty good, but you pay for that consistency, reliability and warranty / life.
