Logitech MX Master 2S

I use this on a work machine, so I cannot install the Logitech software, however even without the software, the mouse works fine. I love how the middle wheel will free-wheel if spun fast enough - this took a bit to get used to, but now I love that feature. I found the button on the thumb resting area brings up the list of open programs on Windows 10, which makes it so easy to "alt+tab" to other programs! Very comfortable to hold in my hand.
