Excellent design, functionality, can use on up to 3 devices at 1 time
This is a comfortable keyboard with the perfect cupped area on each key which will make you a speed typer and all the function buttons are easy to find and use. Wish it had backlit keyboard, The Mouse is a dream – No hand cramps and you can scroll through pages quickly with you mouse’s roller – fastest one I’ve ever had — I use it at work for 10-14 hour days no hand cramping. BONUS: use the keyboard and mouse on up to 3 different devices ie; Laptop, IPad and Phone to send a text etc just set them up. Worth the $ ,

Good quality keyboard and mouse, though mouse is not silent
The wrist rest is very comfortable. It is a full size keyboard. However the first very noticeable thing upon pressing down on a key on the keyboard is that it feels like you’ve rested your head on a memory foam pillow, that kind of feel. And the key release seems to be slow as well. I didn’t use it too long and opted to return it all because the mouse, though of very good quality, was not a silent mouse and I didn’t know that. I ended up by the wave keyboard and mouse combo and that also had a very good mouse but was very silent, both clicks and scroll wheel. Also as for the size of the mouse of both products, it seems to fit very well. Definitely not as large as the MX Master 3S. That mouse is heavy and big.

Perfect for multiple PCs, just a little pricey
As someone who works on multiple PCs at the same time, this thing is perfect. It’s got that great Logitech feel and it switches between devices nice and easy. Sadly, I’m normally one of those people who only complain about things in reviews, but this is one of those cases I have to say this keyboard and mouse is great. The Logi software is also really great, it adds a lot of functionality to the mouse. Having said all that, the only negative is it is a little pricey for what it is.

Not as you would expect, but read my review
I have had a love-hate relationship with Logitech combo Keyboard and Mouse kits. I’m stretching it to even give this kit 4 stars. Use the unifying USB plug and don’t setup as a bluetooth device. I have had this kit for 2 weeks and every single day there have been more than two dozen times I have wanted to launch my super-deluxe mouse off the top of a 20 story building. Brand new Lenovo P3 computer and this brand new wireless keyboard and mouse, and I have been screaming at the mouse all day, every day for 2 weeks. Mouse scrolling 1 page at a time, even though all settings are set to 1 line at a time. You can’t move the mouse with precision, it lags or just goes away for a few seconds then comes back. Uninstalled and reinstalled – HORRIBLE. Finally, after two weeks, I downloaded the Unifying drivers, plugged in the USB dongle and FINALLY!!!! I have a mouse that works.I noticed that every few seconds, in my Windows 11 Pro Bluetooth settings window, the dang mouse would disconnect and reconnect 20 times in a minute. For testing I still have my keyboard connected via bluetooth and so far it is holding up well, but NEVER, Ever, ever, never, connect this nice- but garbage mouse via Bluetooth. You know, it seems to be typical of Logitech. I have never had a wireless combo set where eventually the keyboard and mouse become projectiles across my office. But at least when I want to scroll down with the mouse wheel, it does move down instead of scrolling down will scroll down, then up then down again like a different name-brand manufacturer’s wireless mouse does. Oh that really bothers me. So I typically don’t do lengthy reviews, but what a garbage mouse when you connect via bluetooth (with all drivers up to date), just save yourself the frustration and use the Unifying usb dongle to at least connect the mouse. It works perfectly as advertised and I am now, finally, able to enjoy this wonderful combo set (but I’m keeping the wired mouse close by for a while).

Comfortable angle & functional !
Very easy to set up on my two-screen computer system. I work from home on my computer and do gaming when not working, this keyboard & mouse replaced the exact same one from years ago. I love it and will not use any other brand for it is light weight, durable, quiet and works just great for me.

Lags, feels cheap and it randomly fills the screen with a letter
* update. Now the 2nd keyboard is acting up. Disconnecting from the computer, powering off and back on then reconnecting helps for a couple weeks and then it starts over. At this price I should not have these issues. I have a different logi keyboard that is 5 years old, used daily and never had a single issue. Idk if the quality has dropped or they had a bad run. But dropping my rating to 1 star, these aren’t even a year old and I have to replace them.I bought 2 of these and one is great no issues. But the other is awful. Keys are not responsive and lags, then other times you press a key one time and it repeats the letter across the screen. It isn’t a stuck key because it is t the same key each time. For this price I would expect a much better quality keyboard.

Works well
I love this design and set up. I have one set at home and another at work. The layout of the keyboard is nice. I like the slightly larger sized mouse as well. It works with my laptops and iPad.I don’t want to travel with a mouse/keyboard so with two sets I just switch the dongle between laptops.

This set is more or less what I was looking for and the right cost to value ratio in my eyes. I do enjoy quality electronics and office supplies so my first thought was to buy the MX keys S + MX master 3S but it just didn’t make sense to pay over X3 as much for standard computer equipment, despite its obviously superior design and build. This set is still nicer than the cheaper ones and although it is still plastic all around, seems to be slightly thicker and of higher quality. The switches on both mouse and keyboard make it easy to switch control between my desktop and laptop without the mess of an extra set. The keyboard is as convenient as any other keyboard. It does have an attached wrist support which is nice and easy to clean but too bad that it can’t be separated. The mouse is more impressive and has 3 customizable buttons, lateral scroll wheel control + physical scroll adjustment button. I did set it up but can’t say I’ve used any of those features so far. Design wise not much to write home about, I liked the white touches on the switch buttons and underside of both keyboard and mouse (although you don’t see it if you don’t lift it). I would have liked more multimedia controls on the keyboard. One pet peeve: I preferred my previous keyboards layout for the windows key. The ctrl FN start and alt buttons here are all the same size and textually labeled for both PC and Mac, but I actually appreciated a bigger windows button with the windows logo on it which most keyboards seem to have (not just the Microsoft ones). Takes me a microsecond longer to spot it but time accumulates. All in all this set is probably good enough for 90% of users.

This is the second set that I bought for my wife this time. Works well, I like that you ca switch between 3 different PCs directly from the keyboard or mouse.

It’s a great keyboard and mouse is awesome- but no print screen button. Really? I’m often copying the screen to paste into paint to copy something- so that was a BIG problem. Fortunately you can assign actions to keys on the keyboard and mouse – so after a bit of fiddling around with those – I like the set up even better
