Our After-Sales Service Commitment

1. Quality Issue Handling
   Should any quality problem arise after product installation, you do not need to contact the factory directly. Simply send me the fault details, error codes and video, and I will handle all communication with the factory on your behalf.
   
2. Free Replacement
   Once a quality issue is confirmed, we will send you qualified replacement products free of charge. You are not required to return defective items to China, saving your time and shipping costs.
   
3. Full Responsibility Guarantee
   If the factory fails to cooperate, I will take full responsibility and compensate you in advance. I will then resolve the matter with the factory directly. You will bear no risk at all.
   
4. Response Time
   We will respond to all after-sales issues and provide a solution within 24 hours.
