⚖️ Seller Warranty & Marketplace Dispute Conciliation

Warranty should be claimed if, after following all usage instructions and troubleshooting steps, the clamp meter exhibits failures not caused by misuse, such as manufacturing defects in internal components, display failure not resolved by battery replacement, or measurement circuit issues preventing basic operation. In such cases, the defect is apparent or latent, and repair or replacement is the seller's responsibility under the marketplace's warranty and return policy.
