USB Unifying Receiver - 2 Pack

I lost the original USB receiver for my Logitech mouse and was relieved to find this Unifying Receiver as a replacement. It works exactly as expected, and setting it up was quick and easy. Setup & Compatibility Pairing my Logitech mouse and keyboard was simple using the Logitech Unifying software, which is free to download from their website. Within minutes, my devices were reconnected and working perfectly. This receiver is compatible with multiple Logitech peripherals, so if you have more than one Unifying-compatible device, you can connect them all to a single receiver, which is super convenient. Performance The connection is rock solid—no lag, no dropouts. My mouse and keyboard respond instantly, just like they did with the original receiver. The range is also good; I’ve used it from about 10 feet away without any issues. Build Quality & Size Like the original, the receiver is very small—almost too small! It’s great because it doesn’t stick out much from the USB port, but that also means it’s easy to lose if you’re not careful. I recommend keeping it plugged in or storing it in a safe place when not in use. Things to Consider • Not compatible with Bluetooth devices – This only works with Logitech Unifying-compatible devices, not standard Bluetooth mice or keyboards. • Requires Logitech Unifying Software – It won’t auto-connect; you have to download and use the software to pair devices. Final Verdict If you’ve lost your original receiver or need a second one, this is a perfect replacement. It’s reliable, easy to set up, and supports multiple devices on one dongle. Just be careful not to misplace it!

These work perfectly well as long as you install the Logitech Unifying Receiver app on Mac and use that to pair it with your mouse or keyboard.

(Slightly) Smaller than my original dongle, great price for 2. Paired easily

Update -- Annnd they stopped working..... End I lost my original usb dongle for my mouse, so I ordered these. They were simple to pair - you do need a windows pc- I'm happy with my purchase.

I bought this 2-pack of Logitech USB Unifying Receivers to replace ones I’d lost, and they worked just as expected. Setup was quick, and they paired easily with my existing Logitech devices. Nothing fancy, but they’re reliable and get the job done. Great to have spares on hand, especially when juggling multiple workstations. Would’ve been nice if they came with a small case or label option, but overall, they’re adequate and functional.

The software compatibility works on any Window laptops and PCs as well as Apple Mac products. It's easy to set it up on any device whether it's Apple or Windows. The wireless connectivity is good and it hasn't given me any trouble at all. The speed performs like any mouse would. Keep in mind the size is small so it could be easy to lose it. The price is okay for what you're getting.

I got this to pair with a mouse (M510) after losing the original receiver. But, it failed to pair with it, and it also failed to pair with a Logitech keyboard when I tried that after the mouse failed. Logitech's Unifying software recognizes that the dongle is plugged into my computer, but it doesn't recognize either the mouse or keyboard when I power cycle them when instructed. So, the only thing I can say is that these replacement dongles don't work. Additionally, these are lower-profile than the original dongles. That may be preferable for some uses, but also makes them much harder to remove from a tight USB port.

Easy to use and glad it was a two pack. I can leave one plugged into the desktop and the other in the laptop. It was the swapping back and forth that caused me to loose the original one. These are also smaller that the original so it doesn’t scare me that it will damage the USB port from a bump. Worked on Windows 10 and 11

buen producto, son originales y se pudieron emparejar con mis dos logitech ratones inalambricos.

Setup fácil para configurar ratón y teclado

Lo compre para poder utilizar el teclado y mouse de la misma marca, sin embargo no operaban. Al insertar el USB lo reconoció lo probe en windows 7 y windows 10 y hasta se veia que sumaba al mouse y teclado pero no jalaban.
