Review on 🔌 Renewed Logitech USB Unifying Receiver: Enhanced Connectivity at an Affordable Price by Michael Bustamante

Very small footprint (too easy to lose when not plugged into a USB port). Works great with all Logitech devices compatible with the merging receiver. You don't even need to download Logitech's merging software. Connect the receiver to a USB port that is not obscured by the line of sight of the peripheral device. The installation of the default device driver takes a few seconds. Turn your mouse or keyboard off and on again. And you're done, just like 1, 2, 3.
