⚖️ Seller Warranty & Marketplace Dispute Conciliation

The warranty should be activated if, after following all usage instructions and troubleshooting steps, the pump exhibits a manufacturing defect, such as persistent leaks from the pump body, a broken internal mechanism without apparent misuse, or failure to inflate even with the nozzle and mechanism in perfect condition. In such cases, the product may have a manufacturing defect, and the consumer is entitled to a replacement or repair under the seller's warranty and marketplace return policy.
