⚖️ Seller Warranty & Marketplace Dispute Conciliation

Activate the warranty if, after following all usage instructions and troubleshooting steps, the controller exhibits failures that cannot be resolved (e.g., does not charge the battery even with a functioning panel and battery, displays persistent error codes without apparent cause, or does not power on at all). These may indicate a manufacturing defect.
