I had a friend of mine by a callaway FTI tour driver on ebay and he hit good with it for about two weeks and the ball was just going everywhere after that. He called the company to see about a refund, and they said they had no problem sending him a brand new driver in its place with no charges. When he read them the serial number off of the driver that's when they determined that it was a fake. Companies in China are buying these items and mass reproducing them for cheap. Obviously without the same quality. Companies in China cannot be sued so there are no reprocussions... Do be very careful buying clubs from people on ebay, or anything for that matter!
