This is a Logitech MX Master 3 wireless mouse in Mid Grey, model MR0077. This listing includes the mouse only; it does not include a USB-C charging cable or the USB Unifying receiver dongle. The mouse has been tested and all mechanical functions operate properly, including the primary buttons, MagSpeed scroll wheel, side thumb wheel, and gesture button. There is a small cosmetic tear in the edge of the rubber grip on the thumb rest flap. Because the USB receiver is missing, the mouse must be connected via Bluetooth, or paired with a separate Logitech Unifying receiver using Logitech's pairing software.
