Logitech Lift mouse ($57.47 shipped). Tossed the highly non-ergonomic Magic Mouse that was starting to give me hand/wrist pain. Having also used the MX Master 3 before, I even prefer the (cheaper) Lift. 200% recommend.
did you have to install the software to use the mx master 3? i've been reading a lot of negative reviews about the software eating up a ton of resources, but without the software things like horizontal scrolling doesnt work etc.
