Customer Ratings & Reviews

I bought this for my home office so I could easily control both my work and personal computers with a central keyboard and mouse. Button selectors on each make switching easy enough, but the innovative Logitech Flow software is truly amazing. While it does not work flawlessly, simply holding down the control key and moving to the edge of the screen switches both mouse and keyboard to the next device (You can choose to disable the ctrl key, but I found it switching unintentionally way too often). It even includes clipboard functionality, so things like moving account numbers or email addresses from home to work computer is quick and easy. Works with both Bluetooth and the Linksys unifying fob (1 included), so attaching to any PC or other device is easy as well. Only con I can think of is that it lacks a dedicated Print Screen key, but I adapted to that quickly enough.

Very easy to install. Great Feel to the keys. Mouse fits comfortably in my hand. I hope it lasts!

I decided to upgrade my 520 keyboard to another full-size keyboard that offered the option to connect with multiple devices. I settled on the MK850 and love it. It is very comfortable to use and keystrokes are 'just right' in terms of responsiveness and feel. The switching functionality is simple to set up and use, and is seamless. That was not my experience with a less expensive keyboard that tended to have a lag when switching devices. That is the worst feeling to be typing and seeing blank on the screen. Lastly, the mouse is improved also over the 520 combo, very comfortable and responsive, with additional functions and customization options. All in all, I highly recommend this keyboard/mouse combo.

Great keyboard and very easy to switch between multiple computers.

Easy to use. Wireless. Replaces small keyboard that comes with computer, and is awkward to use.

The keyboard and mouse are very ergonomic and responsive. I love being able to pair these with both my Mac and PC and switch with just the click of a button between the computers! Plus, as an added bonus, Logitech’s Flow software makes my Mac almost like an extended desktop for my PC, and vice versa! With Flow enabled, I can have the PC and Mac open side by side and just drag the cursor to the edge of the screen on one device and (about a ½ second later) it appears on the other device, just like an extended desktop!!! Then you can copy/paste and more from your Mac to PC and vice-versa! I didn’t realize that that the mouse and keyboard was capable of this when I bought it. I figured I would need to get a KVM switch for that. This combo greatly exceeds my expectations. Way to knock it out of the park, Logitech!

I am really enjoying my new keyboard and mouse. Mouse fits great in my hand and the keyboard is very quiet.

I have a gaming setup at home but needed something for work and this was perfect. Keyboard feels great and mouse is responsive and the extra buttons helps with efficiency at work.

The keyboard and mouse is good overall. It has this weird thing where a real mouse has to be plugged in for it to operate like it should. Sort of defeats the purpose. The other issue is the switching between computers does not seem to work as flawlessly as advertised. I set it up on a work laptop and gaming computer and it will work for a day, maybe two, and then the work computer wont recognize the keyboard and mouse all together. I tried the little dogle thing, same thing happened. I finally gave up on the switching (main reason I got it). BUt the keyboard is comfortable, so I kept it for gaming. I also expierence no notable lag between input and action on the computer, which I have expereinced with other keyboards and mice during gaming. So two pluses. But did not really do one of the main things it advertises, so I would not recommend the extra money over a lower model.

I liked the keyboard. I work at home and type a lot so I thought it was perfect for what I needed to accomplish.

The Logitech MK850 Performance wireless keyboard and mouse combo delivers exceptional comfort and efficiency. The contoured keyboard features a cushioned palm rest and quiet keys, while the ergonomic mouse ensures smooth navigation across PC and Mac. With reliable wireless range and customizable buttons, it’s a great productivity boost in sleek black design.

Running 2 pcs (1 Win7/ 1 Win 10). Each had wired keyboard and wired mouse. 2 minute setup. Using one Bluetooth the other using the enclosed USB receiver. Flawless so far.

I absolutely love it! This product has significantly simplified my life, and the quality is outstanding. It’s a game changer that you definitely don’t want to miss out on!

Excellent combo for the price. I have larger hands so the mouse is perfect for me. However the keyboard is slightly long. So, if compact is for you then is is not for you. However great quality and comfortable keyboard wrist rest.

I was looking to replace a corded keyboard and mouse after converting to a stand desk. Both the keyboard and mouse have a comfortable feel to them. They both paired easily to my phone and iPad. Not sure whether I’ll use that capability very often, but nice to know it’s available if in a pinch.

Excellent keyboard and mouse. Very smooth, comfortable and easy to use.

A great keyboard. Nothing fancy. Does a good job. Best feature is ability to control 3 devices without having to play musical fob.

I love the ability to connect it to multiple devices. With the click of a button I can toggle between typing on my work laptop to typing on my mac.

One of the best keyboard I have used. I have used several logitech in the past but this one is ultimate.

I bought this keyboard and mouse to replace the set the came with my computer. The keyboard is perfect for my hands (I cannot say the same about the keyboard that came with the computer). I love the mouse, I often use the extra buttons and I find them very easy to setup and use.
