Lmao, that is the author.

I use the Mx master for work and it’s great. Can be used wired or wireless, 2.4ghz dongle or Bluetooth, and has a regular scroll wheel plus a thumb scroll. The regular scroll has a button to switch between individual steps or free spinning and you can also set it to free spin when flicked hard enough while in step mode. I regularly deal with 500-1500 page PDFs so being able to just flick a hundred pages or so is nice.
