I was using three PCs side by side, with three separate keyboards and three mice. All I wanted was one keyboard to take the place of three keyboards. What I got was so much more. Love the mouse which I hadn’t expected. Mice don’t take up a lot of room, so whether or not a mouse replaces three mice at first didn’t mean a lot to me, but when I discovered how comfortable and smooth this mouse is, I was thrilled to be able to use it with three PCs by the press of a button under the mouse. -So while I still have the original mice connected in case I don’t want to take the 5 seconds it takes to pick up the Logitech mouse and push a button to share the Logitech mouse, because I enjoy using the Logitech mouse so much more, I doubt the old mice will get much use!
-So this keyboard and mouse work with up to three PCs, via LogiBolt or via Bluetooth. I wanted to connect the keyboard and mouse via LogiBolt on each PC. The set only comes with one LogiBolt that is pre-programmed to pair with the keyboard and mouse as computer#1/mouse1. More specifically, straight out of the box I could plug in the included ‘Logi Bolt’ into the USB port of any of my three PCs and it worked with each of Win 7, Win 10, and Win 11 PCs. HOWEVER, I didn’t want to have to keep switching the one LogiBolt among three PCs (and I didn’t want to rely on Bluetooth) so … I found two more LogiTech LogiBolts for sale on Amazon and bought two more LogiBolts.
IMPORTANT: Unlike the LogiBolt that comes with the set, the additional two LogiBolts aren’t plug and play – a few simple steps needed to be done to pair each LogiBolt with the keyboard and mouse. So because this info is surprisingly hard to find, here’s the bottom line:
1) I used the pre-programmed LogiBolt USB Receiver that was included with the keyboard and the mouse on the Windows 7 PC, and it worked plug and play. Both the mouse and the keyboard pair (work with) that original LogiBolt USB receiver as computer 1 and mouse 1.
2) Next I wanted my Windows 10 PC to pair with the keyboard and mouse as computer 2. Since the LogiBolt purchased separately isn’t plug and play, for my Windows 10 PC, I had to use my pre-existing mouse and keyboard to navigate to logiwebconnect.com; and once at logiwebconnect.com website, then I inserted one of the new additional Logibolt USB Receivers (that I bought separately on Amazon) into the Windows 10PC and on logiwebconnect.com site the site recognized the LogiBolt receiver and gave me prompts to ‘add a new device’ to that LogiBolt receiver. Then I pressed the ‘computer2’ key on the new keyboard for 3 seconds to make the new keyboard discoverable by that particular Logibolt, and that’s what pairs the PC with the keyboard as computer2. So now that particular Logibolt USB Receiver sees the keyboard as belonging to computer 2 whenever computer 2 button is pressed on the keyboard. Then on that same logiwebconnect.com website, I was given the opportunity to add another device to that LogiBolt USB receiver, and so this time on the underside of the Logitech mouse I pressed the button until the number 2 appeared and the logiwebconnect.com website found the mouse and is now paired with that mouse when 2 is chosen underneath the mouse. So those are the steps to program the keyboard and the mouse to know they’re connected as computer2/mouse2 with that particular USB Receiver. FYI, in order to do all this, I still needed my pre-existing old keyboard and mouse to navigate the website, etc.
3) For the Windows 11 PC, IF I had had a pre-existing mouse/keyboard for that Windows 11PC, I would simply have used the pre-existing keyboard/mouse to navigate to logiwebconnect.com and follow the same steps I wrote in 2 above, except instead of choosing to pair as keyboard 2/mouse2, I would have chosen keyboard 3/mouse 3. -BUT I didn’t have a pre-existing keyboard/mouse for the Windows 11PC, so I actually ‘borrowed’ the LogiBolt from the Win7 PC and plugged it temporarily into the Windows 11 PC, and so the Windows 11PC immediately recognized the LogiTech mouse and keyboard on a plug and play basis as computer 1/mouse 1. I then went to the Logiwebconnect.com website and PLUGGED IN A NEW LOGIBOLT I HAD JUST BOUGHT ON AMAZON. The Logiwebconnect.com website then indicated that the Windows11 PC had two LogiBolts in it, so I had to choose which of the LogiBolts I wanted to add new devices to. (To make sure I chose the correct LogiBolt to program, I unplugged the original LogiBolt that came with the keyboard and mouse and paid attention to which LogiBolt disappeared from the list. Then I plugged the original LogiBolt back into the same USB slot in the Windows 11PC AND MADE SURE I CHOSE THE OTHER LOGIBOLT TO ADD DEVICES TO.). In other words, I used the original LOGIBOLT that comes pre-programmed with the mouse & keyboard as the #1 option in order to navigate through the logiwebconnect.com website to add that same keyboard/mouse as the #3 option to the new LogiBolt that I bought separately on Amazon. -and amazingly that worked! So if two Logibolts are connected to the same PC, the PC can be paired both as keyboard#1/mouse#1 and as keyboard#3/mouse#3 on the same keyboard/mouse! Once the Windows 11 PC was paired on the new LogiBolt as PC#3 for the mouse & keyboard, I simply unplugged the original LogiBolt and put it back in the Windows 7 PC, with the automatic and immediate result that the Windows 7 PC was once again computer#1/mouse1. In other words, once you pair a LogiBolt USB Receiver with this keyboard and mouse, the Logic bolt USB receiver REMEMBERS THE PAIRING AND WHATEVER COMPATIBLE PC YOU PUT THAT LOGIBOLT INTO WILL PLUG AND PLAY WITH THE KEYBOARD AND MOUSE. The pairing apparently happens at the Logibokt level, not in the PC itself.
Conclusion: I only bought this because I wanted one keyboard that worked with three PCs easily. This set totally does that, once it’s set up (& I purchased two more LogiBolts rather than use Bluetooth to get up to three PC connections). I was delighted to find that this keyboard and mouse are very well made and EXTREMELY comfortable to use. Mouse is particularly nice – nicest mouse I have ever had. Who knew any mouse could be so superior, but this one really is. As a result of all this, after buying the keyboard/mouse set (that comes with one LogiBolt), PLUS BUYING TWO MORE LOGIBOLTS, I am able to easily use this keyboard and this mouse with three different PCs. I never downloaded any LogiPlus software onto any of my PCs, and probably won’t, since the reviews on that software are so mixed. The keyboard lighting is very nice and easy to read. Highly recommend if you have more than one keyboard cluttering your space – and the mouse is so nice I’m so glad I bought the full set. I hope this review is helpful to you 🙂

I have never really been a logitech guy, but after my beloved vertical mouse had issues with its scroll wheel for longer than I could bear, I decided it was time to upgrade. The keyboard is hefty and of absolutely glorious quality. Typing is like dancing one’s fingers across silky clouds. Keystrokes are quiet with just enough of a satisfying click. Configuration is fantastic, with an excellent suite of function keys that double as the F keys, which are set up exactly as I would desire more or less, but are completely configurable to do whatever you would like. I would prefer having them separate from the F keys because I use those frequently, but it’s small potatoes. The backlight is classy, useful and also completely configurable. The mouse… oh the mouse… it’s comfortable to use, much lighter than I would expect, the 8k dpi is accurate like I have never experienced. The scroll wheel and its free wheeling mode is worth the price alone. The thumb scroll wheel is so wonderful that it needs to become standard equipment for all future mice. Gestures take some getting used to, but are innovative and also fully configurable. The flow function and keyboard link is like magic, instantly moving my mouse and keyboard from my work laptop to my home computer when I move the mouse off screen… if you work on a computer for a living you NEED this combo… you do… don’t think about it, and definitely don’t ask your spouse, just get it… you’re worth it tiger.

Very comfortable for your hands / wrists, keys are quiet, mouse is smooth. Amazing product from Logitech. Battery life seems to last a very long time between charges.

Bought this set for work and it’s been amazing. I’ve always been used to having side buttons to go back and forward in browser pages, so having a side scrolling wheel makes me feel spoiled.
The fast scroll wheel is my bread and butter, allowing me to rapidly scroll through my hundreds of subfolders, and change between a free scroll or weighted scrolling (which feels so satisfying when weighted).
The keyboard is flat like a laptop which I personally love, because I type way better on a laptop than traditional keyboard. The blacklight is controlled by sensors, so it will automatically adjust or turn ok depending how bright the office is.
I highly recommend this mouse and keyboard to anyone needing an upgrade.

Okay, so I am cheap and this keyboard/mouse combo seemed extremely overpriced, until I used it! I have a Macbook pro and windows laptop from work and my own personal Windows desktop all connected. The simple button to switch is amazing. I also have an LG monitor which auto switches to the active machine too which is helpful. In all honesty… game changer. I’ve added a bunch of personal macros, like complex things I need to do all the time with the logitech software. It’s got to be the most intutive system I have ever worked with! Also, not having to change from Mac to windows keyboard all day, with three on my desk had been nice.
The mouse is awesome… the scroll wheel is weighted, so you can send it and scroll at mach speed, and it keeps going like like a spin bike wheel. It also has a pile of buttons and toggles which are all customizable.
So yeah, I should have bought this a long time ago! Expensive YES, but do I see why? YES!

The keyboard is great if you have big shoulders. In retrospect, the more ergonomic version would be to have the smaller keyboard because both of your hands would be more aligned.
The worst part – The Logitech Software that you seriously barely can remove on Mac (read forums online how hard it is to remove the software) that tracks all the keystrokes to make this keyboard “easy” to use

Such a treat to use! Didn’t know what I was missing. Will be recommending to everyone.

This combo is great for just about anything. The keyboard feels very good, and I’m even happy after replacing an expensive mechanical keyboard. The mouse itself is fantastic, and really the star of the show. I upgraded from an MX Master 2 (the previous version) and the 3 is a fantastic upgrade. The scroll wheels are significantly better and clearly had a lot more thought put into the design. The back button is roughly equivalent, but the forward button is in a much better place compared to the Master 2. Both devices will switch between up to 3 devices, which works great for me since I do switch between work and home devices often. I can’t come up with a single negative thing to say and will probably buy again.

I’ve used the original MX Keys and MX Master 3 for years and basically couldn’t do what I do without them. I’m a content creator who works with 4 different computers. Due to constant use and too many bags of chips, it was time to upgrade to the S versions. Although each computer has its own keyboard, Hyper X mechanicals to be exact, they aren’t conducive to proper workflow. With the touch of a button I can go to 3 of those computers with nary a hiccup on the MX Keys S. I also, on occasion, use a MacBook Air and all it takes is a moment to Bluetooth and I’m good.
The software, not a real big fan but I think that has to do more with my computers (different windows OS) than the software itself. I Bluetooth and have chosen not to use the Unifying Receiver. The typing experience on the MX Keys S is superb just like the original, no issues there and the backlit keyboard is better than the original, allowing you to control the brightness better. The MX Master 3S is also excellent, working seamlessly with the MX Keys S. Although I love mechanical keyboards, this is just better for my application. I may add a couple of feet to it so it’s raised more to my liking, but it really is a non issue. Battery life is excellent, just a quick attachment to the USB C and you’re golden. I can also work across the office if I’m doing something on another desk. The connection is excellent. I highly recommend this to ANYONE who works with multiple computers….or not, it’s and awesome duo. 100%.
