After-sales service includes order tracking, video guidance, troubleshooting, defective product returns, and overdue repairs. After you complete the order payment, the salesman who communicated with you will inform you of the order progress in time. If you still have other concerns, we will still provide you with detailed answers. The warranty period for all goods is one year. Starting from the date of shipment, if the goods are damaged due to non-human reasons within one year, we will send you replaceable parts for free. If the machine is completely damaged, the machine can be replaced according to the situation. If the machine is damaged beyond the warranty period, we can provide you with paid maintenance services.
