If you receive defective products: 1. Notify us within 30 days of receiving the goods, providing photos/videos of the defect and the batch number; 2. We will verify the issue within 3 working days. For minor defects, we will send replacement parts and repair guides; for major/critical defects, we will arrange free replacement of defective products (including shipping cost) or offer a refund.
