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 Corey Burgess

I lost the receiver that came with my K400+ so I ordered it and after a quick setup with the Unifying software I was able to use it with my Windows 10 - Sync computers. The whole process from loading the app to showing the keyboard took just a few minutes. I finally found the first receiver so I keep it on my laptop and have no problem using the keyboard on any computer. I'm also experimenting with using it with a Raspberry Pi and it seems to work great for that too. I am very happy with this purchase, five out of five gold stars.
