Some of this thread missed a the fundamental point.  It is irrelevant where the balls are made.  All that counts is "quality, cost and schedule".

How good are they, what do they cost, and how long do you have to wait for them. 

...It doesn't matter if a Chinese person or an American person polished your balls. 

Since the product has now been recalled due to quality issues I'd say where they were manufactured has turned out to be extremely relevant.
