Customer Ratings & Reviews

This keyboard has a great touch to the fingers. Easy to use and set up. You will not be sorry to have purchased it.

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

Love this product. It allows you to quickly switch between computers with buttons on the mouse / keyboard, so I can use it for my DT and my laptop and switch in a heartbeat. Keys are uber quiet, mouse is comfortable. Its also pretty responsive for a wireless mouse and I use it for online FPS besides work and don't get much in the way of lag. DPI could stand to be higher so I wouldn't use it for any design work, but it's more than adequate for anything else.

So, I got this as part of a bundle with a computer I bought. It was half off the original price and from what I read it was good, so I went for it. To start it off, love the Bluetooth connectivity! It was very quick and easy to setup. I love the mouse! It is one of the best wireless mouses I have ever used. There are a few buttons I am trying to get used to though. The keyboard is where I am struggling. It is hard to type with but as I use it more it "breaks-in" which makes it easier. Overall I would say you should get it but be patient with the keyboard and enjoy the mouse!

Easy to set up and use with multiple devices. Keyboard and mouse both barely sip any power.

I was looking for a nice quiet keyboard that I could type on without annoying everyone else on an online meeting. Most keyboards that I tried were noisy, to the point of being disruptive in meetings. The only drawback is that the Caps Lock key doesn't reflect if caps are accidentally turned on. And, more recently the arrow keys were working on and off... If they keyboard wasn't so darn quiet (love this) I might have returned it.

works great and was easy to install. I like the keyboard and the mouse.

Good product and ease of use. It has a build to be able to not have your arm hurt

I got this as a replacement for a 17 year old Logitech ergo keyboard and mouse. The keyboard has a great feel. The layout is roomy, but not quite as much as the older keyboard. The mouse feels great to the hand and has multiple customization options.

Very comfortable and quiet. Love the keyboard & mouse combo. And love wireless.

This is a nice keyboard, but with a couple of caveats. The multi-system connectivity is very useful, as is the ability to use Bluetooth connectivity. The downside is that this is not an ergonomic layout, and it begins to wear on the wrists after a full day of typing. Plus, the keys are quite loud, which gets really annoying to those around you. For not a lot more, the K860 overcomes these limitations. Spring for that one instead.

Easy to connect and has a good touch. A good value.

3rd one I’ve bought for various computers. I love the angle of the keys which gives me ease in typing and releases tension on wrists. Great for multiple computers bc it can wirelessly attach to up to 3.

Really like how ergonomic the devices are & how easy it is to pair multiple devices.

Went to store to get a keyboard, but couldn't find the one I was looking for so I bought the MK850 combo. It was very easy to get them going, and the keyboard works great, but I do a lot of CAD work, and the last 2 logitech mouse that I've owned, when the scroll wheel is pressed, it puts the file in pan mode, but this one (in just a fraction of a second) zooms the file to infinity. so I have to go to menu or press 3-4 buttons to get into pan mode. Can't find any way to re-program the mouse, so it's going into the garbage.

This is the closest thing to the perfect keyboard/mouse set! Tested several and returned all. Went inside the store to test this one out before purchasing, and my hands just sat perfectly. There’s not a lot of key travel but definitely a good amount. Highly, highly recommend! Just buy it!! You won’t regret it!

been using this about 2 weeks, got it to switch between two separate computers on a single monitor, it works very effectively (once you get used to hitting the white button for which computer).

I bought this in store. There were so many to choose from. But I really needed a new keyboard and didnt need a mouse. This set is the best. The keyboard has a soft feel to it with a slight raise in the middle of the keyboard. Set up was quick as it was plug and play. I reallly like the keyboard. The mouse is excellent. It has a button under the scrolling wheel to scroll smooth or to make it click when you roll it. Its a bit bigger than a traditional mouse. Overall both components are very nice and I would highly recommend them.

I go from my desktop to my laptop and back. it is great to use one keyboard and mouse for both without having to move anything. The keyboard is shaped well and the keys have great travel and feel. The mouse has an issue I have had with other Logitech mice, it does random moves. Like it will zoom without me touching the wheel and when I zoom out it will zoom in again. But it happens randomly, so I tolerate it for the convivence and the keyboard.

Really liking this keyboard. Only gripe is the cloth like wrist support (seems like it'll get dirty fast and be hard to clean). That's a small trade off for a keyboard and mouse that'll work on up to THREE devices. On my primary machine I use the unifying adapter, on another two I use the Bluetooth. Switching devices is easy via dedicated buttons, and you can auto switch by using logitech flow (being on the same network is required, as-is Bluetooth on additional devices). You can even use it on pc and Mac (has both sets of key labels)!
