Do not buy this MK850 if you have to play games at least occasionally. The mouse wheel is wobbly. It works by itself even with normal movements about the table. In shooting games, the wheel usually switches weapons - it's almost impossible to play. The weapon switches automatically every second. During normal browsing of sites on the Internet, when scrolling down - it also backlashes and constantly scrolls the page a little up - annoying. And this is not a defect of my particular mouse. Many people wrote about this problem, including on English-language sites, I just thought that the smartest, that I wonβt have this, they say, hasnβt Logitek fixed this problem since 2022? Didn't fix it. I found the only way out - I had a mouse from the old Logitek K330 kit - it can be connected to the MK850 receiver - the old mouse works like a clock. Well, the Control key on the MK850 keyboard is small and uncomfortable, you constantly miss during Ctrl-C, Ctrl-V operations - well, you can still get used to it, but not with the mouse.
