Standard Product After-Sales Policy

Standard products refer to products mass-produced according to our company’s standard specifications, with fixed parameters and no personalized modifications; user-customized products are excluded.

1. Service Guarantee Period

1. Basic Guarantee Period:
   Acceptance shall be completed within 7 days of product delivery to the user, and the period is calculated from the date acceptance is passed; the complete unit carries a free 1-year warranty. If acceptance is not completed within 7 days, it shall be deemed as having passed acceptance.
2. Lifetime Service Guarantee:
   After the warranty period expires, we provide lifetime repair service. After inspection, a detailed repair quotation is issued, and repairs are carried out after the user’s confirmation.

   • (2) We complete the inspection within 5 working days of receiving the product, issue an inspection report, and notify the user;
   • (3) For products repaired free of charge within the warranty period, they are shipped back to the user within 3 working days of repair completion; for out-of-warranty or paid-repair products, repair begins after the user pays the repair fee, and the product is shipped back within 3 working days of repair completion.
