Not knowing too much about the machine, it took a long time for me to figure out what kind of machine suits me best. Catherine has given me great help and inspiration during this period. Through her patient work and guidance, I finally got the right machine. During the whole production process, she always updated the production state and progress. This allowed me to get the production process of the machine in real time, which made me feel relieved. The delivery process went smoothly. At last, in the process of installation, debugging and operation, the team of Catherine’s gave us very practical and valuable instructions. They sent two engineers for me to help me complete the installation and debugging, and taught my workers how to use and maintain the machine. I am very grateful for their efforts and hard work.
