The glass/metal material is actually the mid-G-end mouse pad that domestic players came into contact with earlier. One of the great features of glass/metal materials is that the movement is extremely smooth, which will naturally make players feel comfortable after a long absence. If there are more delicate means of operation, then both small-scale precise movements and large-scale long-distance raids can be completed perfectly. Glass/metal material also has a disadvantage similar to that of cloth material, that is, some products are not so perfect in reflection, and the reflection is not perfect. As a result, the photoelectric mouse naturally loses frames, and sometimes the mouse cannot be moved. Phenomenon.
