There are a number of fakes and look a likes for sale:
BEWARE of any PING being offerred on ebay: there are genuine clubs being offerred but there are several fakes and look alikes. Selling a look alike even without describing it in words is illegal. Pictures of a club which leads people to believe it to be a genuine Ping are as illegal as the written word--a deception is intended.
Don't be fooled into believing that the look a like is as good as the real product. It most definitely is not. The fakes are put together with inferior material and inferior finish which adversely affects the performance of the club and will ruin your enjoyment of a great game for certain
All Pings can be traced by reference numbers on the hosel.
Before bidding on any Ping club ask for these reference numbers and in the case of the old style wooden headed KARSTENS ask for plate details and serial numbers.
