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

Works great with logitech m525 wireless mouse. Just needed to go to logitech.com and repair it with the logitech unifying software. After I downloaded it it took me through the steps. It was easy. Awesome mouse too.

I lost the dongle for my K520 Logitech keyboard & mouse over 5 years ago and held on to the keyboard and mouse because I could not bare to part with it. Despite several horror stories of not being able to get a new dongle to sync properly with the K520 K & M and not being able to return, I took the chance! I am happy to report that I am currently typing on my old K520 keyboard and using my M310 mouse!!! It took me less than 5 minutes to download the Logi options + software and sync the mouse and keyboard. If you love your *orange star* Logitech keyboard and mouse and lost the dongle - this receiver will work! Buy it and get excited!!

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.

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.

5/5 Rating My Dad's computer went on the fritz 2 weeks ago. Come to find out he needed a new hard drive. Before he took it to the repair guy I instructed him to remove the Logitech MX Master 2S dongle transmitter in which he did. I didn't realize it would get lost shortly thereafter. I was kinda upset because the mouse won't work without it. Good thing these dongles were sold individually. Ordered one, it arrived 2 days later. Super easy to connect. Just download Logitech connecting program and it pretty much syncs it with whatever mouse or keyboard you have. Super simple. Crisis adverted. Pros Easy to use Super easy to connect to Logitech peripherals Affordable Cons None

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

Good product, easy to connect and now i can use my mouse

Had to buy it separately from compatible hardware good to have the ability to buy replacement receivers in case one gets lost

Works great. Remember this isn't plug and play. You need to go to the Logitech website to pair your device to the dongle. If you have a Mac there are some extra (kinda annoying) security sets you have to do, but it walks you through it. Was able to pair an old MX Performance mouse to a MacBook Pro.

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
