For gaming not the best mouse. But for everyday use for work, damn! It's just so much more ergonomic and tha weight adds to that comfort. There is no need for DPI upgrade for me, I see this as a "work" mouse, not a gaming mouse.
Smart move to boost sales of Master MX 3S by renaming it while making insignificant changes. Heavy, Plasticity meh whatever they call it MX 4, 5, 10. The greedy corporation will never make it full metal which left us no choice but go with Chinese brands.
I like the MX Master because it's heavy. Polling rate increase would be fine, The DPI is sufficient, even 400 dpi on the original Microsoft optical mice was more than enough. Chasing spec numbers for the sake of it doesn't help usability.
If you want a gaming mouse for playing FPS shooty bang bang army games then buy one of those.
The successor to the Logitech MX Master 3S appears to be on the horizon, as Logitech has accidentally published a first image of the upcoming flagship mouse. Meanwhile, an official certification in Brazil reveals more details.
