It is (unfortunately) an old generation MX Master. At the same time the 2S doesn't do anything amazing.

Hello, the mouse is indeed a Master 2S, this can be seen in the software that you have to install to get all the features.
Now, there is almost no difference between the two, I own them.
The only difference is the copy from PC to PC, but do we really need that in the age of the cloud?

Have a nice day.

For me, I would have said an MX Master 2S. The MX Master has a "connect" button on the bottom and not the MX Master 2S.
