Callaway clubs assembled in China

I also bought the Callaway X20 irons on okay. I was shocked to see the "Assembled in China" sticker on my clubs when I opened them. I called Callaway and they told me to look at the 8 iron. It has a 10 digit number on it, if it's a real Callaway set. It had the number so I called Callaway and they said the number was not in their data base.
I was told by the gepany I purchase them from on okay and he told me that Callaway doesn't always update their data base. He assured me that they were authenic and I could send them back if I wanted to but rest assure they were Callaway.
After reading serveral articles about fake clubs on the internet, I believe these clubs a real Callaway. My friend has a set he bought from a golf shop and they are the same.
I think Callaway would like everyone to buy from who they authorize to sell there clubs and don't want people to know that their clubs are indeed assembled in China.
