No easy to spot fake clubs.
The best way to avoid it is to buy from an authorized dealer.

Today, fakes item are reproduced with realistic cosmetics and fonts to not specialized persons.
But, one think is sure, the quality and performance won’t be the same.

On internet resale platforms is the good way to get screwed. Not always. If it is to good to be true, it is maybe not true.

So caution,

Only buying from certified Titleist vendors is obviously the best. All Titleist products should have serial numbers that you may be able to verify by calling customer support.

However, I highly recommend buying from a reputable Titleist vendor that way if the product is defective in any way Titleist will work with you to make things right.

If you buy your equipment from an authorized Titleist dealer, then you won't have to worry about "fakes".
