New Logitech Unifying USB Receiver for Mouse MX M905 M950 M505 M510 M525 M305 M310 M315 M325 M345 M705 M215

Had an expensive logitech mouse missing the receiver. Noticed it had the unifying symbol on the bottom. Ordered this and followed simple download and directions and it worked great. Only took a few minutes.

After losing the receiver for my Logitech M570, my absolute FAVORITE mouse, I was just about ready to buy a new one, when I realized that I could simply buy a new receiver and save some money. The receiver arrived in a small package, but was incredibly easy to install and use. The only thing you must do is download a piece of software called Logitech Unifying Software”. Once you install that and go through the setup, the mouse works perfectly, just like it used to. So to reiterate, the mouse is NOT plug and play. You have to first download the free software in order to begin using your mouse with the new receiver.Overall, if you have a more expensive Logitech mouse, and you’ve managed to lose the receiver like I did, buying a new receiver is a quick and easy way to get back to using your favorite mouse, all while saving money.

I've been having the Logitech 510 mouse and nano unifyer for a couple of years, and I LOVE this mouse. It's fairly large and feels good in my hand. It has worked perfectly with the unifyer, even with it plugged into the front usb port on my card reader - until last week. My mouse was suddenly not being recognized on boot, and was intermittently losing contact with the computer during use, sometimes going from being recognized to not being recognized continuously. A Google search shows that quite a few people developed this problem and resolved it by pulling the end off and inserting a small piece of paper on the circuit board, and gluing the end back on. I did this and it did work, but I ordered this new nano unifyer and am now keeping the original as a backup. I already had the Logitech Unifying Software installed and as soon as I ran the program and followed the directions, my mouse was back in action and hasn't had a problem since. I'm a happy camper. : )

Update - Contacted the vendor and he said the this device does not work with my Logitech wireless mouse and keyboard. Partly my error, I assumed this device was for all Logitech wireless devices. Be very careful ordering this device. Perhaps request compatabilty first...Original Note:Lots of good reviews and I have never had any issues with Logitech components. Sadly this does not work for meHardware - MX550 keyboard... Logitech wireless mouse (I cant read the model the writing is too small)1) Plugged in the receiver... Windows 7 loaded all the driver correctly. Great I thought this will be a slam dunk2) Loaded the software unify program. Booted up. It found the receiver3) It says turn the device on and off... and it will register. Well my devices did not after many attempts.There is no help. It either works or it doesn't. I tried in several USB ports NADA. The ports are on the front of my computer. I put the mouse real close when trying to register.My issue1) Device Doesn't work (windows 7 and MX5500 keyboard2) The keyboard does NOT have a switch to turn on and off. How do i register this device !!3) The Logitech original software does not recognize this device either.4) When I went to the help site my webroot software said it has fishing issues !!! Red flag.Is this hardware legit... !!!Beware..

Great Product.. Great Price.. I lost the unifying receiver that came with my mouse, and needed to get a new one. Either that, or a new mouse. But the mouse (M505) was a really good mouse and had great battery life, so I checked on Logitech's site and would have to pay over $20 bucks to get another receiver. basically what I paid for the mouse originally.... So.... Checked on Amazon and found a new part for 4.99. didn't know if it was going to work, but for 4.99, what the heck. Anyway, got the receiver in several days. and now all is well. Mouse is working without any problems!!Would definitely recommend this seller!!

And by the way, first place I've mentioned it but Bing's wonderful AI lied to me about this. Had to abandon s-mode to run Logitek unifying software which is easy as pie. Devices work flawlessly. However, my underpowered computer that s-mode was designed for is now clunkier ad suffering from the change. and you can never go back!PS, otherwise would have given all fives for the product in question.

From the order date to delivery date I waited less than a week. Based on a review by another customer I took a chance and ordered this unifying receiver. I purchased a Logitech Revue about a year ago and after Logitech discontinued this product they also cut off users from receiving Netflix software updates and in general, satisfaction with their device. I don't watch much television and therefore rely heavily on Netflix to get my fix. After thinking about recycling my M700 keyboard that came with the Revue I found out I could purchase a Unifying receiver to get my keyboard sync'd to my laptop. Longer story short, laptop is connected through HMDI to my Westinghouse LCD screen and te laptop is set to do nothing when I close the lid so I can stash it without having to deal with it out in the open. All I have is a screen and my keyboard on my desk. Pretty sweet set up. The only problem I have is with my keyboard. There is a loss of functionality when it comes to using it with any other device than the Revue. Not a problem. It won't function as a full keyboard but that is to be expected. It was not made to be used with a pc. All in all, very content with my purchase. Although, I may have to consider purchasing a mouse. The thumb pad on my keyboard is a bit cumbersome and I could benefit from having something a bit more responsive.
