⚖️ Seller Warranty & Marketplace Dispute Conciliation

Contact warranty service if the spring exhibits hydraulic oil leakage, complete jamming without apparent cause, or significant loss of closing force immediately after installation, indicating a potential manufacturing defect. Issues like excessive noise after prolonged use or cover corrosion in non-aggressive environments may also be covered under the seller's warranty and marketplace return policy.
