Logitech Unifying Receiver for Mouse and Keyboard (Renewed) …

The receiver itself worked great. I could pair it with my newer wireless mouse and it worked perfectly fine. I was worried about some bad reviews on this refurbished version, but it worked OK and also looked almost brand new. It doesn't come with instructions; just the receiver in a little bag. You have to download the Unifying software from Logitech's website and use that to pair your peripherals to it.However, you have to make sure your peripherals support Unifying before buying this. They have to have the little star logo somewhere on them. I originally bought this as a replacement for a lost receiver for a Logitech Wave keyboard and mouse combo. Since the one on Logitech's website is sold with a Unifying receiver, I assumed that this one would work just fine. However, it wouldn't pair with mine, because apparently I have an older model of the exact same keyboard that doesn't support Unifying. Just be sure your peripherals have the logo on them, and you'll be fine.

I was skeptical at first due to some of the negative reviews, but took a chance anyhow. For those that may not be aware, these receivers are not perfectly plug n play. You will need to download the Logitech Unifying Software in order to pair the receiver to a list (up to 6) unifying Logitech mice and/or keyboards. The download can be found here: [...] There is also a Linux hack that works really well with the Logitech Unifying hardware. The only downside to the pairing is that most (maybe all) Logitech devices only allow one receiver to pair with. So, if you pair with one receiver, then any other receiver the device was paired with is effectively ignored by the mouse or keyboard until the Unifying Software is ran again to pair the target device to the target receiver. Even though that is a bit annoying the nano-receivers work as advertised.

Did NOT work at all.

I was given a wireless Logitech keyboard/touch-pad second hand, but it had no receiver. I also have a Logitech mouse that I lost the receiver to. So I purchased this to hopefully get either one or both to work. Thankfully, it works great. All I had to do was use the unifying software on one machine, and that receiver works on every other machine I used either or both accessories with. Set up once, get some batteries, and you are all set.

Had to download additional software to handle the set-up (notice or instructions not included in packaging from what I saw), but worked as intended afterwards.

I have an M570 trackball that has the orange star logo on the bottom of it. The original unifying receiver that came with my M570 has the orange logo as well. I broke the original receiver and did not want to purchase a whole new trackball. I just received the Unifying Receiver from this listing and it does not work with my M570! The original receiver that came with my M570 looks EXACTLY like the picture. The one I received looks different than my original and different than the picture on this listing. Hopefully I can return it. If not, at least it was cheap!EDIT: I actually got it working. The issue was that it did not automatically pair. The solution was to install the unifying receiver agent (Never had to install it before) and manually pair the device. My issue was compounded by fact that I was trying to do this on a work computer that is locked down and I could not install the software. I had to use my home computer to pair the device, and then I was able to use it on my work computer without issue.

Should be a BIG GLARING DISCLAIMER - this does NOT work with Linux, maybe with Apple. This is a Windows-only toy that even has complaints in that department. Great idea, but there is no functional support for this receiver in Linux (a couple of programs claim they support it, but forget it, you'll never get them to work properly).

Hi Guys Lenny hereI plugged this little guy to my laptop and it worked like a charm. I like the fact that I saved a little money. before I bought this, I saw some people had some problem with this because it is a refurbished unit, but I decide to get it anyways, Im glad I did now i can use my Logitech Mx Master with my laptop. I wanna let you know that i downloaded the logitech software before plugging it in, i hope this help you.
