Hello,

As a user of the MX Master 3S for several months, I would like to provide feedback on some improvements I would like to see in future versions. Firstly, I want to emphasize that I am very satisfied with this mouse.

Its silent operation is very pleasant, and the scroll wheel is excellent. The software is beautiful and easy to use. The build quality is very good, with only minor gaps in the assembly. However, I work at the quality in the aerospace industry, so I might be overly demanding.

Here are a few issues I have encountered:

Wrist Orientation: When holding the mouse, the entire weight of the arm rests on the carpal tunnel. This can become uncomfortable and even painful over time. I also use the CADMOUSE PRO WIRELESS by 3Dconnexion, and its angle is perfect. You should consider taking inspiration from it.
(That the worst mouse weaknesses !)

Thumb Button: The thumb button requires shifting the thumb to access it. It would be better if it were positioned further forward, or ideally, placed on the body below the two shortcuts buttons.

Additional Functionality for macOS: It would be great to use the vertical scroll wheel to quickly switch between desktops. This could be achieved by using the scroll wheel for scrolling and translate the wheel by the left or right to switch desktops.

Please feel free to contact me if you would like more detailed feedback. I would be happy to help.

Have a great day,
Best regards,
Max
