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

MUST download the software to pair any unifying compatible mouse that has an orange star. Google "Logitech Unifying Software". Not that hard folks, works great!!!!

Found a K400+ at Goodwill for $2 missing the receiver. Got this and paired it up near effortlessly. It's easy to use, has great range, and works with multiple Logitech devices, freeing up my other USB ports. It felt a little pricy, but still cheaper than a whole new keyboard. Plus it's a one-and-done, so can't complain too much.

Nice update for my old receiver.

I purchased this only to get an error 404 message when I attempted to connect it. After being on the help chat through the Logitech website for two hours, I was told that this is no longer supported, and that I would have to buy a whole different unifying Reciever. Now I am not able to get a refund even though I ordered it a month ago.

The item is a USB Unifying Bluetooth receiver for any Logitech device that has the Unifying icon (which resembles a 6 point black star in an orange background, although to me it looks like a black sprocket). I bought this item so I could use a Logitech M560 mouse that I had lying around without its dongle. At first, the item was not recognizing the device, but a little research in the Logitech's website for product M560 provided a driver for Windows 11 for the dongle, which worked perfectly. The only issue I have with this specific device is that the black knob is too small for a good grip and so it requires some effort to remove it from the laptop on which I installed it, because it's one of those thin-line laptops that have a jaw (like a mouth) in each USB 3 port which makes plugging in USB devices a pain. But other than that, it was great value for the money.

it connected to my Logitech keyboard but it is really power consuming. you have to turn off your keyboard or remove the batteries or you will be changing batters every week.

My wireless keyboard receiver went bad, it was easy to install with the Logitech software. Setup was easy and am very happy I didn't have to trash the keyboard

I bought it for the Logitech K350 and it worked immediately. I love that it was compatible and worked right away.

Funcionando perfeitamente.

Works well. Needs pairing with the device.

Picked up a cheap second hand ergonomic mouse that didn't come with adaptor. This paired easily with it and works without any concerns.

Buenísimo!!! Muy fácil de adaptar y configurar, funciona de maravilla, muy recomendable, hay que bajar el software a la computadora y listo, muy rapido

with my wireless logi keyboard. works nicely
