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 Johnny Wheat

I have an M310 mouse and a K520 keyboard and my key was broken. I bought this merging receiver and it worked right away after downloading the merging receiver software. Follow the simple instructions and as long as your device is listed in the site description you should be able to get the job done. This $15 unit was cheaper than the $50 replacement kit and will work with additional units if needed.
