Mice compatible with Logitech's Unifying receiver are those with the orange Unifying logo. Recent compatible models include the MX Master series, the MX Anywhere series and the M720 Triathlon. These mice can be paired with one or more Unifying receivers, allowing up to six compatible peripherals (keyboards and mice) to be connected to a single receiver. Logitech's Unifying software makes it easy to manage these connections.
