After-sales Service
Last Updated: September 2026
Our Commitment
We are committed to providing high-quality industrial laser modules and professional technical support to every customer. Every product undergoes rigorous testing before shipment. If you encounter any issues during use, please contact us at any time — our technical team will respond within 12 business hours and assist you to the best of our ability.
All Sales Are Final — No Returns for Change of Mind
Due to the specialized and technical nature of industrial laser modules, all sales are final. We do not accept returns or exchanges for the following reasons:
• Change of mind or no longer needed
• Ordered the wrong model or specifications
• Incompatibility with buyer’s equipment
• Price difference or found a cheaper alternative
Please carefully review product specifications before ordering. If you have any compatibility questions, contact us for consultation prior to purchase.
30-Day Quality Replacement Policy
Every unit undergoes rigorous testing before shipment. If you receive a product with a manufacturing defect or functional failure, please follow these steps:
1. Notify us within 30 calendar days of delivery at szjg70633860@gmail.com, including your order number
2. Provide clear photos or a short video demonstrating the issue, along with the product serial number (if applicable)
3. Our technical team will evaluate the case and provide an initial assessment within 2-3 business days
4. If a manufacturing defect is confirmed, we will replace the product with a brand-new unit within 3 business days and provide a new tracking number
5. All round-trip shipping costs for quality-related replacements are borne by us
