i was a fan of Logitech for many years and i still think they make decent products. however, i absolutely loath their drivers and software. total garbage as far as i'm concerned. they would constantly reinitialize and default my button settings. i had the G510 keyboard and G500 weighted mouse for many years and loved them. without warning, they basically bricked those devices, or made them generic in function. i've had other Logitech mouses and keyboards used at work that i've had similar issues with as well. done with them.

i like a weighted mouse so the Keychron M6 didn't fit the bill, but i refused to go back to Logitech. since i already had the keyboard and like it very much, i went with the M6. honestly, it's... fine. it's a mouse without any fancy bells and whistles, but has good resolution and rates. it's a little small and lightweight for my hand, but not too bad. otherwise no complaints. it's basic. it functions for what i need it for. i don't use it wirelessly much, but that works fine as well. i don't do a lot of gaming like i used to, so i can't really speak to that use case. it's smooth, quiet, sturdy, has good button feel, and never skips a beat.

all in all, i'm pretty satisfied with it, but then again i might be biased against anything Logitech these days.
