Beware of buying titleist pro v1 golf balls . I did and as a user of these balls knew right away they were fake . They differ in so many ways .How to spot them :  1. to bright a white cover 2. too hard 3. rought parts on cover 4. slightley smaller 5. all 12 balls in box are stamped with NO1 and not NO 1-4 as is normal practice.
