Hi
I recently purchased a second hand 910F (with a Diamana Kai'li 75 shaft) online and noticed that the "certified authentic" sticker on the shaft doesn't have the "Titleist" logo on it and also doesn't have a serial number. It is the usual silver sticker (which appears to be polairsed) with the orange/green top and some hologrammatic writing. It looks legit - it just has no serial number on it.
The serial number on the head of the club is 259442W. It came to me second hand from a shop in Adelaide, South Australia.
Just wondering how concerned I should be that the club is a fake.
Thanks
