⚖️ Seller Warranty & Marketplace Dispute Conciliation

Activate the warranty if, after following all usage instructions and self-resolution steps, the controller exhibits failures not caused by misuse, such as not turning on, not charging the battery under full sun, or showing visible manufacturing defects. In such cases, the defect is apparent or latent, and repair or replacement is the manufacturer's responsibility under the seller's warranty and marketplace return policy.
