LogitechUSB Unifying Receiver - 2 Pack

My office colleagues are always tossing the USB receivers but keeping the keyboards and mice. I saved them and bought these replacements. I now have wireless keyboards and matching mice for life.Note: Logitech software is needed to register a receiver with a wireless keyboard.

It worked when I downloaded a software. I just googled Logitech unifying software and then paired mouse and keyboard separately.

Easy to use. just download the software from logitech and you are ready to go in less than a minute. remember to check if your mouse/keyboard is compatible with the unifying receiver. im using the m310 mouse and k540 keyboard with no issues.

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!

No problems with product, just a little annoyed that they didn’t come with my master mx2s

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 worked with my k400 and k400+ keyboards.

Great product, great price and quick shipment!
