| Comparison Description | The upper and lower covers of the keyboard are matched with buckles. The gaps between the two covers are uneven. The buckles are not tight enough and easy to loosen. The buckles are exposed which affects the appearance. | The upper and lower covers of the keyboard are fixed by screws at the bottom, which is very firm. And the matching position is hidden at the bottom to ensure the surface could be more beautiful. |
