⚖️ Seller Warranty & Marketplace Dispute Conciliation

Warranty claims should be made if, after following all self-resolution steps and ensuring correct usage, the speedometer exhibits functional failures not caused by misuse. This includes manufacturing defects in electronic components, seal failure causing water ingress under normal use conditions (light drizzle), or if the display shows visible manufacturing defects that do not disappear after cooling.
