Bai, Grace 一、The significance of negative reviews to importers and e-commerce sellers
Negative reviews are direct feedback of consumer dissatisfaction, which can help importers and e-commerce sellers understand consumer dissatisfaction, thereby improving product quality and customer service, enhancing user experience, avoiding receiving negative reviews again, and thus improving business performance. One of the effective ways to avoid negative reviews is to conduct strict pre-shipment product quality inspections at the source of product procurement, and to improve the importer’s supply chain quality management level with the help of the professional experience of third-party inspection companies, which is also a common practice in international trade.
二、Common negative reviews of telescopes and analysis
1.Optical performance defects
| Product Description | Telescope | |
| URLs of sources | https://item.jd.com/100017742567.html | |
| Screenshots of consumer complaints |  | |
| Product defect details |  |  |
| Possible sources of the problem | – Insufficient lens grinding precision, low image clarity – Misalignment of prism assembly, resulting in ghosting or chromatic aberration – Too large gear clearance in the focusing system, inaccurate positioning | |
2.Fragile structure and insufficient durability

Possible sources of the problem | – Plastic parts use recycled materials and lack impact resistance |
3.Packaging and transportation damage

Screenshots of consumer complaints |  |
Product defect details |  |
Possible sources of the problem | – Insufficient compressive strength of outer packaging (e.g. corrugated box weight < 300g/m²) |
4.Product appearance and cleanliness defects

Possible sources of the problem | -The lens cleaning process did not meet the standards (e.g., not wiping clean); -No visual inspection during assembly (fingerprint residue) |
三、How to avoid negative reviews through professional inspection?
1.Pre-production source control: material and process verification
Review the lens material (such as whether BAK4 prism is used) and the seal ring aging resistance test report to prevent inferior raw materials from entering the production line.
2.Process dynamic inspection: key process supervision
Focus on monitoring in the assembly process: lens cleanliness (no fingerprints/dust), screw tightening torque (error ≤5%), and waterproof glue application uniformity.
3.Packaging and labeling compliance review
-Check the product parameter marking (such as magnification, objective lens diameter) and the actual measured value deviation ≤5% to avoid “false propaganda” type negative reviews.
-Check the integrity of accessories (such as instructions, cleaning cloth, warranty card). In one case, the proportion of complaints about “missing accessories” due to missing eyepiece cover reached 18%.nliness defects
Telescope Quality Inspection Core Checklist
