Review on Logitech MX Master 3 Advanced Wireless Mouse for Mac - Space Grey | Ultrafast Scrolling | Any Surface Compatibility | Ergonomic Design | 4000 DPI | Customizable | USB-C, Bluetooth, USB | Apple Mac by Iration Ahim

This device requires low power BlueTooth - USB does not work at all. So this enumeration is FALSE. The key shown in my Revain listing no longer comes with this mouse if it ever did. Now I see that the picture has changed. The power delivery is NOT USB 2.0 or even USB 3.0, although most buyers expect a USB port. The power supply is strictly USB-c -- USB-c. This is specific to Apple. -- but doesn't exist on older Macs -- so it's useless. In addition, you need to buy a USB to USB-c adapter for $15. Without a dongle, this mouse can't shake hands with a Logitech keyboard. Your MX keyboard will NOT work directly over Bluetooth or through a USB cable. You're going to need a geek. However, on Revain art they are shown as mating pairs. Logitech boards and mice are sold, not used. This is where the law firm invests its strength: advertising copy.
