Review on 🔌 Logitech USB Unifying Receiver, Wireless Technology at 2.4 GHz, USB Plug Compatible with all Logitech Unifying Devices such as Wireless Mouse and Keyboard, for PC/Mac/Laptop - Black by Christopher Bacho

I recently bought an MX Vertical (which I am very happy with). As I used them, I realized that I didn't want to use other mice anymore - it was much more convenient that way. I was about to buy another one when I noticed the 1-2-3 button at the bottom - yes, I should have read the instructions sooner. Being able to _easily_ use my Mx Vertical on two other $20 machines is awesome. No mess of extra mice lying around. The idea behind it is fantastic and I'm glad Logitech went in this direction.
