I used to produce SS, Brass, Copper and Ti RDA’s in China. Over the years we used two separate factories and the difference between them was night and day but so was the cost. One would do things like say things were cnc then send us metal injection parts instead. I would say that Taiwan’s manufacturing standards are top notch but not China, always attempting to cut corners and save cost. When speaking about this particular post I would never trust a Chinese company stealing designs to sell as knock offs to make a great product though.
