5. Smell the smell, the new machine has a faint sandalwood fragrance, which is different from the general detergent and perfume smell. The body must not have sticky wax and oil (if there is, it will be beautified by JS).

7. Check whether the gap between the seams of the shell is uniform and below 1mm, whether there are pry marks, and whether there are pick marks at the two sealing points under the screen in the upper cover.

8. Compare the elasticity of the buttons and the brightness of the internal and external display screens with the new machine.

9. Carefully look at the fixed gong nails of the fuselage for spinning, painting and ink (you can use a magnifying glass), and whether the trademark has pry marks.
