Customer Ratings & Reviews

Amazing. Been using them for 3 years now and still great to use.

As plug and play as you can get. Very convienent for my ergonomic user requirements.

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.

easy set up, easy use. No problem at all. Very light touch on keyboard

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.

Keyboard is really smooth and the mouse is great too. Definitely more comfortable to type on than my previous.

Excellent product. Very versatile and comfortable 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!

This keyboard was really good making to finish my work faster with ease of touch. The mouse is really awesome, able to connect three devices via BT, help seamlessly switch between devices. Highly recommended one.

Nicest keyboard I've ever had. Key motion is very smooth

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.

easy setup, nice feel, helped ease my wrist pain, can work longer without hand discomfort

I love my mk850. One of the best keyboard oars mouse combos I had and had many. Logitech are the best

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 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.

This is a uniquely technical gadget that allows you to display characters onto the computer screen by pushing the coresponding button on this board. Additionally there are secret combinations that allow for whimsicle hiddlen characters or operations ... what a time to be alive!

The keyboard is easy to set up. Just plug in the wireless fob and it's ready to go. It comes with two AAA and a wireless mouse. The keyboard is ergonomically designed so it is comfortable when typing. The overall layout and feel of the keys are great. My only issue with the keyboard is after a month it just stopped working. Nothing I did helped. I tried replacing the batteries with no success. So, I returned it. Maybe I just got one that malfunctioned.

This keyboard is awesome. No need for multiple keyboards. It works flawlessly. Highly recommended

This my second time buying this combo. My first one is almost 10 years old and still works like a champ. I got a second one for my 2nd office. the keyboard and mouse are comfortable and the mouse is intuitive to start using. High quality product that will last. Well worth the $.

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.
