Logitech USB Unifying Receiver, 2.4 GHz Wireless Technology, USB Plug Compatible with all Logitech Unifying Devices like Wireless Mouse and Keyboard, PC / Mac / Laptop - Black

I plugged this into a USB switch connected to two difference computers allowing me to switch my MX master 2S between the two computers with a single button rather than having to swap profiles.Very easy to set up, tiny thing that sits underneath a solid wood desk with no connectivity issues so far, very happy.

Great product, vastly improved the connection to my Logitech MX Master 2s

On my usual rummage through the local charity shop, I found a wireless Logitech keyboard but it had no unifying receiver. So hence the purchase!Arrived well packaged and all intact!The device itself it exceptionally small as expected, so no large, dongle sticking out of my PC. Its only 3mm in size not including the USB connector which you don't see because its inside the pc/laptop.TO ADD DEVICESYou may have to download and install the Unifying Software from the Logitech website. It would of been nicer however if you just plugged it in and the software installed automatically. Plus I didnt see this in the instructions, I was just lucky enough to watch the video on the amazon website.You can add up to six devices with one receiver if need be which is pretty cool because Ive now connected my mouse and keyboard to the one device leaving me with a spare USB port on my PC. (Always a good thing!)I trust Logitech devices having used many of their products over the years and as expected this one does the job seamlessly. No loss of contact with the keyboard or mouse so far!Would have been a five star review but for what it is I personally feel its a little over priced, plus Im certain it doesn't mention anything about downloading additional software in the instructions. So for that it looses a star but overall, I'm still very happy with my purchase and would highly recommend it!

This Logitech USB Unifying Receiver performs great with devices that support it. However, be sure to check compatibility before buying—it’s not compatible with the K380 keyboard. If your devices are on board, it’s a reliable choice!

won't pair, you have to download software before you can use the usb receiver, pointless if you can't connect your mouse or keyboard to download !!!!

I used this to replace a lost logitec keyboard for. Worked well.

Okay, so I got this having left my wireless mouse in the office and thought it would be easier to use this to connect another mouse I had. My main issue being my laptop only has 2 USB ports and I needed 3, if I was going to use each devices, separate dongle.I didn't get to try this as the 'unclear' part of the description, is that it only works with specific Logitech unifying devices, not just any Logitech wireless device. Ultimately, my fault for not really doing enough research but the concept is sound.I returned this to Amazon and went with a hub,to give me the needed connectivity.

Works well with my MX Master 2S. It also remembers the wireless connection, so you can use your mouse in BIOs or other computers without having to resync
