Logitech C-U0007 Unifying Receiver for Mouse and Keyboard Works with Any Logitech Product That Display The Unifying Logo (Orange Star, Connects up to 6 Devices) (C-U0007)

Lost my keyboard receiver when I left it on a remote computer. Ordered this replacement after confirming on the Logitech website that it would work with my K400+ keyboard and trackpad. Received dongle and plugged-in. It did not work right out of the box. I read the very tiny info sheets that came with the receiver to no avail. Finally Googled and went to the Logitech website. For a Mac computer, you can program the receiver via software that you can download. I really wish Logitech had better instructions with the receiver and on their website. But, in the end works great - even at 1/2 the cost of a new keyboard, lol.

Product works super well! Compatibility with my Logitech Mouse was great! Very easy to use and pair with your device. Simply make sure that your device and the receiver have the same tag before buying this product. Also, download the app for the Logitech Unifying Software first before you get this product!

Does not work with Logitech wireless mouse M505 nor with any of my Logitech devices. Downloaded software did not recognize it. No 30-day gaurantee on this item. The writing on the package is all in Chinese so you don't know what you got. NON REFUNDABLE ITEM. DO NOT BUY AMAZON needs to state clearly that this is non refundable.

Does what it’s supposed to do. Just works.

Works clearly and easily upon setup, only complaint is that the instructions on the package were not in english and the link it tells to visit does not work. If you're confused, just look up USB reciever in the logitech downloads section of their website and install the reciever program.

Perfect use, easy, good quality. NO moving parts, so it should last forever. Tiny, no real lag time, fully functional plug and play.

Working great no Problems

This receiver didn't work from day one. I had bought a Logitech MK850 keyboard and mouse combo whose receiver stopped working, very early on, within the time of purchasing my combo. I was working from home and couldn't find info on Logitech website about how to get a new receiver so I decided it would be faster and quicker to receive it, if I ordered it here on Amazon, seeing I couldn't find info readily on Logitech's website. I received the receiver and went to use it but noticed that it didn't fit snug into my USB port, on my computer. I then noticed that the receiver is shorter than the original receiver, the width of it, inside is smaller, and it doesn't have an orange piece inside, it's black. It almost got stuck in my new computer. I am now stuck and can't use the keyboard and mouse because I can't find the right unifying receiver I need. I logged onto Logitech's website, and it wasn't too much help. See photos for differences. In1st photo the one I purchase here is at the bottom (the shorter one) In the 2nd photo the one to to the left is the one I purchased. You see it is hollower inside and doesn't have that orange piece that they say should be inside a Logitech unifying receiver.

Great device, but need to find the right location to download the application, the link given does not exist.

Working fine. It did not come in Logitech packing so that seems to be a drawback although it seems to be a genuine product. Had to download a software from logitech website and it immediately recognized my wireless keyboard. Essentially i had to buy this because i seem to have misplaced the wireless receiver for my KBD. Since it support up to 6 devices it might be helpful in avoiding a clutter with other logitech wireless devices I may use.

compatible with Logitech devices that use the Unifying receiver - my MX Master keyboard and MX 2 mouse. NOT the newer Bolt devices. Lets me use my mouse and keyboard on two devices.

Llegó un día antes. Solo hay que ir a la página de Logitech y bajar la aplicación Logi option+ y listo. Fue fácil y ya estoy cómodo con el uso. Lo recomiendo, muy buena opcion

Works well. Easy to pair.
