Excuse me, which laser engraving machine in China has better quality?

Domestic laser engraving machines are relatively large: Yueming, Boye, Jinyun, Tian Kai and Sangong. Due to the low technical threshold, there are thousands of small enterprises. After more than ten years of development, the technology has been relatively mature, and most companies are fighting for prices. No matter how cheap the machines on the market are, some people still dare to buy them. The machine quality of big manufacturers should be stable and the service should be good. However, the company has a lot of money because of the high advertising fee, many personnel and high cost.
