Logitech Unifying USB Receiver, 2.4 GHz Wireless Technology, Compatible with USB Port and All Unifying Devices such as Wireless Mouse and Keyboard, PC/Mac/Laptop - Black

I just lost my original usb receiver during my business trip. I was quite annoyed by myself because i thought I was generating rubbish (the mouse and keyboard) by losing the usb receiver. Then I found this product and watch a few online videos (can find some easily on youtube). Actually found that it can work with mouses and keyboards that are not in the compatibility list. Then I give it a try and it works!. Mine is K260 keyboard and M210 mouse. I think they call it MK260 online. They are quite low end Logitech product that I bought them three yrs ago that maybe just £15. Anyway, the key point is that this unifying receiver was advertised that it would work with devices with receiver originally with the unifying receiver logo. I think it is very misleading and is not true. This unifying receiver can do more! little tips: when using the unifying software for connecting the devices, it maybe better to use 'advanced' button instead of pressing 'next' (see attached photo). Also, if your device doesn't have switch to switch your mouse on and off (as described by the instruction on the unifying software), just remove the battery and plug it back in to mimic the switching on. Good luck! hope this helps. I am quite happy that I do not need to throw the mouse and keyboard away. better for environment!

There's quite a few clones around plus Logitech's own 'nano' receiver - which is larger than this one. This is the 'pico', the smaller product for the lowest profile - great if you don't want to notice it, e.g on the side of a keyboard or back of TV. This is similar to the one that comes with the Logitech MX Anywhere series mice and works perfectly well with them as a replacement. But you can also use multiple ones if you have multiple Logitech devices or a device that has multiple channels, such as the MX Anywhere series mice. This can be handy if you want your mouse to control your PC and, say, a smart TV or box on your desk - just put a receiver in the smart TV (most support it these days), and change the channel with the push of a button on your mouse. It makes navigating Netflix, YouTube or Prime much easier if you TV doesn't have a 'mouse remote'. Frustration free blister pack for once - just press it out from the back instead of fighting your way thru the razor sharp plastic. Seems a no-brainer - get the genuine product with the lowest profile for only a few quid more.

I bought this as I got a new laptop at work and I left my original reciever in my old laptop (rookie mistake, I know). The first thing that strikes you is the size of this, it really is tiny! This would be an issue if you need to remove the reciever regularly. I've knocked off one star, as you must use the Logitech Unifying software to actually use this and pair with your mouse or keyboard. This can be an issue if you're using a device which does not have administrative rights (and managed by the organisation). However, there is a way around this which seems to have worked. I used my personal computer at home to download the software and pair the device, and once I put the reciever in my laptop at work it seems to have rememebered the pairing! In all it seems to be working pretty well despite the initial set-up issues!

I cannot speak for other devices but I can say that my experience is that this is not compatible with the Logitech MK270 Keyboard and Mouse when I tried to pair it I got the message "The device you are trying to pair is not Unifying compatible. Please use the receiver that came with your device." which is not very helpful as I bought this to replace a lost receiver! I have used a lot of Logitech equipment but now will be much more sceptical I have also had problems with their receivers before having to mechanically reposition the board in the receiver a couple of times, a well know manufacturing flaw of Logitech and will get another make of Keyboard and mouse for now.

Have three computers each with a logitech universal dongle so can control all from single mx keys keyboard and m702 mouse. All works perfectly. If you download the software you can tie both the keyboard and mouse to each specific receiver in turn . You can repeat for any other receivers you have on that computer - you dont have to install the software to all the computers you just need it on one to do the set up and then you can remove software if you want. Once you have tied the three devices slots on the keyboard/mouse to each dongle you just plug them into the respective computers. Really usefully it works on BIOS passwords / bitlocker at boot which bluetooth devices dont seem to.

The device has functioned exactly as described, however this is a replacement for an identical device that failed me after a year or two. The failed device started intermittently disconnecting and I was forced to go through a reconnection process. Not such a problem in itself as this process is straightforward but after a time the device failed completely. The keyboard I use with this device requires a unifying reciever, so I'm now commited but given the option now I would purchase a keyboard that had a permantley connected reciever rather than the unifying device. It does have the advantage that a number of components can be connected to the same unifying reciever although in my case this is not an advantage. I have never had a problem with any fixed devices ever. My advice to you is to stay fixed.

After the USB receiver for my M570 wireless trackball ball was damaged courtesy of the family Baskerville I thought I would have to buy another mouse or tolerate my very basic 'emergency contingency' mouse. While scrolling through Amazon I spotted this unifying receiver and thought it might be what I needed as both my mouse and keyboard were Logitech wireless items. Some of the reviews I read before deciding whether to purchase were a little concerning but the 'admin' stated clearly it was compatible with the M570 mouse and K800 keyboard, both items wearing the orange star logo. Bought it, installed it, downloaded software. dead easy as I'm still an IT luddite and it does exactly what it claims on the tin, well, cardboard packing leastways. Over the moon with the product and it has freed up a USB port on my laptop as well plus, I have the capacity to add another 4 mousey keyboardy thingies should I need to.

I needed to connect a new Windows 11 PC to my Logitech MX Keys and MX Anywhere 2 mouse. Plugged the receiver in and with a bit of fiddling with Logi Options software it works perfectly. I now have my three computers with one keyboard and one mouse. It's a bit expensive for what it is but I'd rather pay for one that works with my stuff than one that might not if that makes sense. Recommended.

Der Logitech Unifying USB-Empfänger ist ein echtes Must-Have für alle, die mehrere Logitech-Geräte nutzen. Mit einer kabellosen 2.4 GHz Verbindung funktioniert der Empfänger zuverlässig und ohne Verzögerungen. Was ich besonders schätze, ist die Möglichkeit, bis zu 6 Geräte gleichzeitig zu verbinden – perfekt, um Maus, Tastatur und andere Logitech-Produkte ohne zusätzliche USB-Ports zu verwenden. Der Empfänger ist klein und kompakt, was ihn ideal für unterwegs macht. Die Kompatibilität mit PC und Mac sorgt dafür, dass ich ihn auf allen meinen Geräten nutzen kann. Eine ausgezeichnete Wahl für eine saubere und effiziente Arbeitsumgebung! Klare Empfehlung!

This thing works as it should.

Mi suegro tenía un teclado Logitech K360 al que se le rompió el receptor, así que lo metió en una caja y lo dejó en el salón acumulando polvo en la librería. Les visitamos el fin de semana pasado y al verlo le pregunté por él y me dijo que no funcionaba, le pregunté si quería que lo intentara arreglar y me dijo que no, que no lo iba a usar, así que le dije que me lo llevaba. Llegamos a casa y vi que lo que le faltaba era el receptor. Busqué el modelo en logitech a ver si se podía comprar un recambio y la página es un desastre, así que lo único que saqué en claro es que tenía la "tecnología unifying". A partir de ahí, me metí en Amazon y busqué. Encontré varios (me decidí por éste por plazo de entrega) y probé suerte. Ha llegado hoy. En un sobre. El envoltorio es el de la casa, plástico duro amoldado para recoger el receptor y las instrucciones de uso. Conectas el receptor, vas a la página de logitech, te instalas un pequeño programa (tienes que ser administrador del equipo o al menos tener la contraseña), lo ejecutas. Te pide que enciendas el dispositivo que quieres conectar (es cuando me he dado cuenta de que no tenía pilas jajaja), lo detecta, por seguridad te hace escribir algo y confirmar que es lo que has escrito y ya está. Te pregunta si quieres conectar algo más y si no tienes más, has terminado. De haberlo conseguido la semana pasada el ratón vertical seguramente lo hubiera intentado comprar también de Logitech, pero vamos, no me voy a morir por tener dos conectorcillos en el portátil. Muy recomentable. Fácil de instalar. Uso sencillo.

Keep up the good work
