I have to write about the wheel, because it's one of the best wheels I've tried. It's a classic "stepper" wheel, it feels precise, high quality, it's quiet, it goes easily, and even its grip (middle mouse) has a very sure grip, a joy to work with, but why I especially like it is its function, when it can work as a "spinning wheel" and not that it physically spins, you don't even need to switch its mode, just give it a quick spin and the page then scrolls itself without the wheel physically spinning. So it's a bit of "fake" spinning, but it works great, both in win11 and in ubuntu - and without any software installed, it's a function of the mouse itself. I like the wheel more than, for example. the Logitech MX master 3 which I also have (I find it heavy and clunky and the grip stiff), or the Logitech G502 X (even clunkier, super noisy and switching modes with a terrible switch). The scroll wheel is probably the best thing about this mouse, And the worst thing is the software, after installing it in task manager 7, in words SEDM processes that deal with the mouse and its profiles for applications. I froze Firefox immediately, after killing the 7 processes it woke up again. And those 7 pieces of crap are taking up 250MB of memory! I had to uninstall it immediately. Otherwise, the mouse has a nice shape, the extra button is a good thing, but the nice wheel makes it seem a bit unnecessary. Otherwise, the buttons don't seem to be quiet, who cares, they make a classic "click": ). Mouse accuracy seems fine to me too. It's a good mouse, but it still seems a bit expensive for being wired.
