Logitech - USB Unifying Receiver - Black

Works well with the MX Mouse and keyboard so now I can switch multiple devices pretty quickly

title yes it does indeed work as listed. It wont explode into flames like most modern tech.

I purchased the Logitech USB Unifying Receiver to go with a Logitech MK850 Keyboard & Mouse combo I have. I wanted to use the same keyboard & mouse on two different P.C.’s The set-up was a snap and the Logitech MK850 Keyboard & Mouse combo worked right out of the box, no issues with the USB Unifying Receiver that came with the MK850 keyboard. The keyboard & mouse have corresponding numbers on them to indicate which device is active, so you would think it would be “brain dead dumb” to set-up the second P.C. & USB Unifying Receiver, right? Not quite! Here’s where the only issue I have with this USB Unifying Receiver & the Logitech MK850 Keyboard & Mouse combo comes up. First the software has to be installed on both P.C.’s for the Logitech MK850 before you can set the Keyboard & Mouse combo to the number you want for the second device, no big deal (the keyboard & mouse default to number one) After turning on the second P.C., the mouse worked correctly, but the keyboard was another story. The software instructions tell you to turn off the mouse and then turn it back on to assign it the corresponding number (1,2 or 3) No problem, these are on the mouse & keyboard. That worked fine, the keyboard doesn’t have an on/off switch, so you have to remove one of the batteries! Then put it back in, and then assign it the number you want it to be. The instructions make no mention of this! Once I got everything set-up, I've had no issues! After having & using the Logitech USB Unifying Receiver in conjunction with the Logitech MK850 Performance Full-size Wireless Optical Keyboard and Mouse combo for a month, I have to say I love this set-up. I highly recommend this Logitech USB Unifying Receiver. It works like a champ!

Once you get the software on your computer and teach the dongle the device you want to use, the dongle memorizes it and you can then use it wherever you want without needing software on whatever device you use it with. Very happy with this purchase

This is a great product if you want to connect many mice or keyboards to your system. But you have yo make sure that you mice or keyboards have a logo on them that enable them to connect to it.
