Quoted from hassellcastle:In addition. Kudos to Stern for alerting them to the issue and them immediately overnighting our customer brand new updated flipper bats. New bats from Chicago to Dallas in less than 12 hours.
Bottom line, Stern received a bad batch of bats. It can happen in any business/industry that receives parts from several manufacturers. With a small run of 100 the problem was discovered after the fact. Stern was PDQ with helping customer get back up and running.
Point being, they didn't qc these pins, at all.
