I'm very satisfied with the Logitech MX Master series that I've been using while developing...
I'm currently using 3 and 3s, and except for the problem of the white rubber wearing out, I'm satisfied and continue to use it by replacing the switches.
It seems that MX Master 4 will be released soon.




It is said that the chronic rubber problem will be solved in this version, so I am looking forward to it.
It's said that an Ai button will be added, but I guess I'll have to see what function it will have...
Since it's a new version after 6 years... I'm looking forward to its release.
