All our products are guaranteed for one year in case of non human damage. You can contact and provide feedback on any issues in a timely manner. We will provide you with free repair services or replacement with new products according to the actual situation. Thanks to our professional quality control team and strict production management system, our after-sales rate is basically maintained below 1%. 

        For orders with after-sales problems, there is also a professional after-sales team to handle them uniformly and promptly solve the problems for you. During the pre-sales or after-sales process, we can collaborate with the R&D department, software department, and quality department to provide technical support in all aspects for customers who have any technical questions or involve software/hardware customization in bulk procurement. We can answer your questions and provide solutions.
