1. Pre-shipment Video Inspection We value trust in every cooperation. To ensure completely transparent and satisfactory delivery, we implement a strict Video Inspection policy before shipment. We will send you detailed videos and photos of your specific order (including function tests and packaging) for your confirmation before loading.
2. Quality Guarantee & Returns We reject sloppy, low-cost inferior production. If there are any non-human-caused quality issues or manufacturing defects found upon receipt or during the agreed warranty period, we take full responsibility.
- Non-Human Quality Issues: For functional failures not caused by improper installation, misuse, or external accidents, we offer free replacement parts, repair guidance, or product exchanges based on the specific situation.
- Claim Process: Please contact our support team at changzengcao@gmail.com with clear photos, videos, and a description of the issue. Our engineering team will evaluate the problem and provide a solution promptly.
3. Shipping Damages Our products are packed with robust, standardized export packaging. However, if damage occurs during transit, please record it on the delivery receipt, take photos of the damaged outer packaging and the product, and contact us immediately so we can assist you with claiming compensation from the logistics carrier.
