I agree with you for the most part. There are some exceptions I think. In the case of Apple, it is my understanding that Apple products are designed and engineered in the USA, then they use cheap Chinese labor to produce them. In this way, quality can generally be controlled and maintained to an acceptable standard. Where as a "pure" Chinese product, quality usually takes a back seat to cost. Scratch that, quality always takes a back seat to cost!
In the case of this Hyet polisher, I do suspect it is purely a Chinese product, from design to production. Hence my reservation. It is interesting though with its digital display and all. That's why I am looking for more user reviews on it.
Another thought on the digital display. I'm really surprised no other manufacturer has come up with this yet. It is kinda cool! I think the next level would be a small LCD screen that would display the same information and perhaps even more info as well. Interesting in deed!!
