The contents of the product are correct. It’s rare to see a keyboard without the center sponge.

Default function of all four knobs is to adjust the volume only, so you have to set it again to use the advertised function.

Knobs use a different contact than the hotswap socket, so you have to choose between the knob function and the normal button function.

Then talk about driver, the text on the driver is very small and there is no zoom function.

There are a lot of options for adjusting the lighting effects, but the operation is not intuitive.

FN keys and FN layer are fixed, so there is no way to make any edits, and it is not possible to change the FN keys and their related functions to other keys; this is a bit different from the advertisement of “all keys programmable”.

Function selection in the mouse button area does not have up, down, left, right, scrolling, which should be one of the most suitable functions for a knob.
