Its interesting how Chinese antiques are so highly regarded, but modern Chinese products aren't...
As someone living in Asia, It boils down to quality control - if you demand a certain level of quality from your factory, you can get it. I've been dealing with this very thing for the past 12 years.
I have a Chinese Benro Carbon Fiber tripod and one of their most expensive ball-heads for my photography...I couldn't ask for better quality pieces of equipment. Even though both the tripod and the ball-head are their top of the line products, they are still half the price of and every bit as sturdy as the alleged best tripods and ball-heads made in Switzerland and Italy by the so called big guys of the tripod industry.
So I agree that if quality control is applied,the Chinese can make a product every bit as good as anyone. Pentax makes their cameras in the Philippines and their lenses in Vietnam and because of their quality control, their stuff is a good as Canon's for example, that are made in the home plant in Japan. It is all about qc. Obviously whichever parts of the WEPS are made in China, rigid qc was applied.
Best to all
