The iD we add to a ball is a "post production" process whch means this is applied onto the ball by us, after the ball has been manufactured by one of our product partners. We include CARE INSTRUCTIONS with each ball that must be followed in order to extend the life of the iD. We DO NOT warranty the life of the iD as this is impacted by many factors outside of our control. With the appropriate care, the life of the iD is indefinate, and will last beyond the balls warranty period of 12 months.
