LogitechUSB Unifying Receiver - 2 Pack For Personal Computer

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 & CompatibilityPairing 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.PerformanceThe 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 & SizeLike 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 VerdictIf 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!

Worked well with my devices.

Couldn’t get it to work then I realized I had another unifying receiver in the room and the application that binds the receiver was attempting to communicate with the second receiver. Once I unplugged the second, everything worked properly. Plugged the second back in and all was well.

I have two laptops, an HP ProBook 6450b and an HP Elitebook 840. I only had one mouse (M325) with one unifying dongle, so every time I switched computers, I kept having to take out the dongle and put it in the other machine. I thought this 2-pack would remedy that problem. But the mouse does not register 2 dongles, but only one. So, every time I switch computers, I STILL have to switch the one dongle registered to the one mouse to the other computer. So, there is no solution trying to use 2 dongles with one mouse.I'll return these and instead purchase a second mouse with it's own dongle for the second computer., and, funny enough, the price for that is only about the same as for this pair of dongles I am returning.

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 got this after researching and confirming through information read on here that it would work for my KBM combo Logitech K270 but it did not work.To save you all sometime as well, be prepared to get a non English pamphlet. You will need to go to the Logitech website and download the software for this and then attempt to pair it when running the set up wizard.Hope it works for you!

They work good

Great Universal Receivers, But No US WarrantyThe Logitech USB Unifying Receivers are perfect for connecting multiple devices seamlessly! They work universally across Logitech products, making it easy to sync keyboards and mice with just one receiver. However, note that the pack I received was from China as the entire packaging was in chinese and didn’t include a US warranty. Despite that, the performance has been excellent so far!
