| Comparison Description | The button is small so it’s inconvenient to press, and the silicone
button is easy to get stuck. | The operation button is upgraded and the surface of finger pressing
is enlarged, which is easy to press. The structure of the silicone
button is upgraded to solve the problem of easy getting stuck. |

| 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. |

| Comparison Description | There is no guidance of the external keypad opening size at the
bottom, and the opening size needs to check in the user manual,
which is inefficient. | After the upgrade, it adds an opening size diagram at the bottom
when the keyboard needs to be drawn out, which can be viewed
immediately without having to read the manual. |
