Updated field: b5, d9, g3, g6, h2, h3, h6, h10, h11.Updated b5/additional information received: the customer reported that they "use the headlight for all specialties.There was no specific event.As seen in the comments the physicians interviewed felt pressure on their heads or it hurt".The customer subsequently provided five different serial numbers with corrected product id (90600).The customer was again unable to state which serial number was linked to the reported surgeons' dissatisfaction.Corrected d1, d4 (product id).The duo headlight and carrying case (90600) was not returned for evaluation; therefore, failure analysis could not be completed due to the lack of information received to perform a complete investigation.Based on the reported complaint, the probable root cause for the customer disliking these 90600 duo headlights is most likely due to customer preference.The reported complaint could not be confirmed.
