Dear Customer, We regret any misunderstanding regarding your order. Prior to shipment, we provided clear product photos and confirmed with you that the controller was not included. Although it was not part of the original agreement, we still offered a controller at a very low price and even promised to send it free of charge. Unfortunately, a dispute was submitted without further communication. Regarding the reported incompatibility, our products were fully tested and verified before shipment. We requested photos or videos for verification, but no evidence was provided, limiting our ability to assist. We remain committed to professional service and technical support and sincerely hope for further communication to resolve this matter. Thank you for your understanding.
