We have bought many machines from Perfect Laser. Some of them are for our own use and some are sold to other companies. We have also purchased equipment from others Chinese companies, but the comprehensive cost performance of Perfect Laser is higher. Although there were some minor frictions in the process, their after-sales staff helped to deal with them timely, and the after-sales service was very good. If you have the idea of purchasing equipment, you can focus on Perfect Laser.
