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

Easy to use, a little expensive, but did exactly what I needed and works perfectly upon setup. My keyboard works great again!

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

Lost my mouse's receiver when IT grabbed all the work computers in cyber event. Was super upset as the mouse was a gift from a good friend. Then I found there was a replacement available and purchased it. I wasn't sure it would work, but the downloaed software had both the mouse and receiver paired in a blink of an eye. I was thrilled. Thank you Logitech!
