Did it job for me when I had lost old receiver
Perfect replacement for misplaced original, works great!
Worked right out of the package!
Arrived timely and my mouse is working wonderfully with this receiver. be aware the receivers are smaller than they used to be, they are easy to drop. Have a flashlight handy in case it falls under your table.
Works fine.
Paired well with a MX Master 3 mouse with my MacBook. Just had to download the Logitech software to pair the receiver to the mouse.
I ordered this unifying receiver because I had lost the one that I had for my mouse (logitech). I ordered this, it arrived quickly and was easy to install. So glad I didn't have to buy a new mouse!
I was able to connect easily once I down loaded the software.
Just what I needed to make my nose jive with my Apple
This was super easy to install, just download the software, plug in the USB receiver, and turn on the devices.
Using two unifying receivers now, and zero lag when switching to either computer! Wish I had done this sooner.
Quality of item was prime. Delivery was superior. Notably fascinating packaging. Remarkably pleased.
It works perfectly well with my Logitech mouse MX Master 2X. I got this mouse in the past, but lost a receiver from it, so I had to buy a new one, and this receiver works well.
I needed this very badly. I ordered it and it came as quickly as promised. Excellent quality.
Got this for my keyboard and mouse. Excellent product
I just connected the usb and you can now use the wireless keyboard, excellent purchase
The usb drive was good but required a driver to be installed. Overall support was good
This USB is the smallest unifying receiver there is. Look at pictures for comparison. The USB has a matte black texture making it sleek and blending in with most computers.
I was unsure it would pair with my keyboard that is compatible with the unify receivers. You need to use a download off of the Logitech website but it worked! I just followed the instructions and once it is paired you can plug and play anywhere. I love it
I lost the dongle that worked with my Logitech K780 keyboard. My work computer does not have Bluetooth to connect to the keyboard, so I ordered the Logitech Unifying receiver to see if it would work with the keyboard. All I had to do was plug it in to my computer and connect it to my keyboard. It works great. I now have my work computer connected with the Logitech receiver, my phone and my laptop (connected via Bluetooth) all working on the same K780 keyboard. I haven't encountered any problems at all with connectivity or speed.
I was worried about replacing the dongle that came with my mouse and keyboard. My keyboard worked fine but, my mouse worked sporadically. I purchased the this USB Receiver, plugged it in and my mouse and keyboard worked instantly! I wish I purchased in sooner.
Was super easy to get connected and download the software needed and immediately connected to my mouse. Made sure it worked on a separate laptop and was great!
someone had lost the original dongle. I bought this one, plugged it in, and it worked like new.
Plugged it in and re-paired with my track ball and all is good now.
Solved my problems so I'm happy
This new one allows me to switch between hardware seamlessly
Great product working OK, installed 100% I recommend.
I never thought I could put it on by myself, it was like something automatic, I hardly had to do anything.
Lost my USB receiver, so I ordered a new one to link my wireless keyboard and mouse. Super easy to set new one.
I bought this because I lost the little transceiver that came with my mouse. Months later I found it, now if I lose one I will have the other. HOORAY
It was very easy to use
Works like a charm
Good product
This product works exactly as advertise, provided you know what you're doing.
I couldn't be happier with the performance from the dongle OR the keyboard.
The user will have to load the driver. In this application, I am just using it to replace my lost mouse USB plug on my laptop.
Need to install a software to be able to pair the mouse and keyboard with the USB receiver. Easy to install and pair.
Easy install
Worked great for pairing an extra keyboard and mouse together.
My daughter lost the receiver that was plugged into her laptop so we ordered this get her wireless mouse working again. It took little effort to get everything plugged in and working again.
