sells for $39.99 with a 1k polling rate sensor (shipping is expensive from keychron). the scroll wheels aren't as smooth and responsive as the mx master, but the overall appearance is very clean and simple, and the shape is a pretty close fit. one of the two thumb buttons sits a little low, but i think it's fine. it's just a work mouse, so i'm not flinging it around or doing anything crazy with it. it has an infinite scroll wheel, similar to the mx master, and it seems fine. just like the mouse wheel feel, the scroll lock button isn't as smooth/quiet as the mx master. i don't care. it's 40% of the price.

idk if this model will stick around. i don't see it for sale anywhere else. amazon does have the 4k sensor version. it's a little more expensive.
