Customer Ratings & Reviews

Original mouse and keyboard stopped working on my all in one. This installed easily and works great.

Great service, great product! Your team was very helpful.

work good easy to install work great with all devices

Comfortable keyboard and mouse. Installation was easy with simple instructions. Unfortunately the keyboard stopped working after five weeks. The Logitech website was difficult to navigate to find the actual troubleshooting instructions. Tended to direct me to pages that told me all about the product but nothing on how to fix it. Once I stumbled upon the troubleshooting instructions they proved no help - one of their step instructions was to change the batteries and then turn the keyboard "ON" before proceeding to the next step. There is NO obvious "on" switch anywhere on the keyboard so I tried to find the on-line manual showing all the keyboard features - There is no manual. Tried their customer chat line - Waited for nearly a half hour to get through the 15 people ahead of me. When my turn came I got the notice "Connecting...." and waited and waited and waited. Finally after 10-15 minutes I hung up. All I wanted to know is where the heck is the "ON" switch or Key to turn the thing on!

Good luck with this model, however, kinda scared of Logitech products after failure of two previous keyboards.

best monitor I've used in a while. Easy pairing with multiple devices. Seamless switching between devices. Long battery life.

I love this setup for my office. The setup can connect with up to three devices using the Logi receiver, or Bluetooth, and you can switch easily between them. This allows me to work with both my desktop and my laptop using the same Kb and Mouse. I love the "Flow" function that connects both computers and switches automatically the device by browsing to the edge of the screen. It also makes copy-paste between computers a breeze. The mouse hast the fast scrolling option by selecting the "free-scroll" or normal scroll. I can go faster through large spreadsheets or long documents.

Well I guess I'm one of the lucky ones, no real problems other than user error and that had to do with pairing the mouse and key board. Once I got it as it should be, it's been working like a charm... The keys are smooth when type, the palm rest is comfortable, My old wired dell keyboard was sent to the retirement place for old key boards. For the price the K850 is getting the job done so far. At this time it gets 5 stars from me..... let's hope the 4 stars remain, I'm not a 5 star kinda man.

Love this keyboard. 5/5. The Mouse isn't bad, but not great either. 3.75/5. I got this since I work from home. I can jump from my work computer to my personal computer easily. I only use the mouse for my personal pc for web browsing. I use a wired mouse for my work pc. I would recommend. Side note, when I got this product early on, I tried to connect it to my PS5. It was not supported. Not sure if that was Logitech or Sony issue, may be patched later on unsure. (This doesn't change my overall rating.)

The keyboard and mouse are stylish, easy to use, and all I had to do was plug in the Bluetooth Unifying Transmitter in a USB, press the white #1 button for 3 sec and it was ready to go. Lots of good features on this on this product for the price. Logitech is a very good product. The MK850 replaced the Logitech MX5000 keyboard and MX100 mouse I had been using since 2007. I only replaced them after the mouse started freezing up. I highly recommend the MK850 and optical mouse combination.

Purchased for a conference room with multiple computers. Changing between them works seamlessly, and the high quality of both the mouse and keyboard compliment the room nicely. Freed up an extra mouse and keyboard, and the switching happens near instantly. Would definitely recommend for anyone who needs to work accross multiple PCs, though I'd opt for the MX keys and this mouse given my druthers. I prefer the smaller footprint and lack of roller wheels on the mouse, and love the toggle-able hyperscroll feature.

This is such an ergonomic keyboard. I have really enjoyed this keyboard. Easy on the hands.

Really easy to install and sync with my computer. Could have used bluetooth but went with USB. Keyboard is very comfortable and the soft keys make typing a breeze.

Some ergoniomic keyboards are too much. This one is just right. Also easy to install.

Solid feel, good key feel, easy setup but did not install any special drivers. Mouse fits my hand perfectly, but definitely for right hand users.

This keyboard is epic. It is so comfortable and the keystrokes feel great. The mouse is really smooth and fits perfectly in my hand. The only problem now is that I don't like my other keyboards or mice. sooo yea. That sucks. They got me! I haven't figured out all of the buttons on the mouse yet, but im sure when i read the instruction and use them they will be very helpful too. I have had this product for almost 3 months and I would buy it again in a heartbeat.

This is a great addition to your home office. The keyboard is comfortable and the mouse is easy to use.

I bought this keyboard for work. It is very ergonomic and does not have the loud sound when typing on the keys. All the letters are responsive and no lag when typing.

I have 3 of these for 3 different computers and have purchased them all at different times. I bought my first one, then I needed another and then later another. I really love them - they work great, good keys and the mouse and keyboard stay connected - super easy setup, takes only a minute or less. This does not feel cheap which I would hate. There is a reason I keep buying this, great equipment. Would buy again.

High quality keyboard and mouse. The battery lasts a long time (months). Buying a second one for the home office.
