Corsair offers excellent gaming mice and keyboards with many great features, such as: Custom RGB lighting, profile modes, macro support, and fine-tuned performance settings. Most of these require iCUE, Corsair's proprietary software, which is great but works only on Windows. If you have a Mac, you'll need to contact third-party drivers to get the features you've paid for.
CKB-Next is the actively maintained branch of the original CKB was abandoned by the creator. You want to download and install the latest version, although you can build it from the source code as needed.
After installation, connect your device and it should appear as a new tab in the Settings window. From here you have support for different profiles and can configure the lighting effects for each zone on the device. The animation effects work well with third-party apps, and while not as intuitive as iCUE, they do the job.
To set up the number pad on a mouse As with the Scimitar, you must click each button one at a time and set this key to enter the appropriate key. It's boring, but it works. The Typing drop-down menu contains a list of all characters for which you can configure the mouse.
Among the other drop-down menus and tabs, you will find modifier keys, function keys, mouse keys, and mouse wheel actions.
One thing the software lacks is a macro system. It has a very simple setup, but seems to only enter one line of text. For example, in macOS you can use BetterTouchTool to configure macros, although I found it too slow to use in games.
On the Performance tab, you can configure the DPI settings and set different DPI levels with different colors, at least for mice that support it.
The Sniper setting is a manual setting that you can activate with another mouse button. It reduces (or increases) the DPI value while holding down the key, and is useful for making accurate shots in games where you normally have a high DPI value. CKB is still third-party software and not without error:
- It takes about ten seconds for CKB to recognize your mouse. During this time, the mouse works, but only with the default settings and delays when moving.
- This adds a little delay to overall mouse operation.
- I did not have the number keys in certain applications, possibly because of the way these inputs are sent to the system.  The initial setup of the mouse is confusing and takes a while
. Add to that the fact that even a third-party program is a big problem, especially with Corsair. However, I did not expect to find a community port created by iCUE for Mac and Linux, thanks to the developers of this app.
