⚖️ Seller Warranty & Marketplace Dispute Conciliation

Warranty should be claimed if, after following all instructions in this guide, the flashlight exhibits failures that cannot be resolved (e.g., does not charge even with tested cables and power sources, LED does not light up even with a charged battery, physical defects not caused by misuse). These may indicate a manufacturing defect, as covered by the seller's warranty.
