Logitech MK850 Performance Wireless Keyboard and Mouse Combo

[This review was collected as part of a promotion.] Bought the mk850 specifically as I had a number of devices. It's has seamless ability to switch between devices which means 1 keyboard and a nice clear bench to work from.

I have been a long time user of Logitech products, however this is a replacement to a Mouse/keyboard system that would allow me to use 2 computer with one monitor and only one mouse/keyboard combo. Even with a failure of your setup, I still am now using two different mouse/keyboard wireless system and still using both computer with minor frustration. Thanks

I work between two independent laptops that cannot know about eachother and this keyboard is so easy to use and seamless in all my transitions. The mouse is a great addition but I wish I could turn off the 3rd pairing mode because I only use two and I always have to cycle through it and it takes a little longer to make my transition.

Top of the line wireless Logictech keyboard. The mouse can work 3 different screens at the same time. Very simple to set up. Has a comfortable hand base and can be tilted and locked upward. Connected to my PC with no problem. Keyboard nice and wide. Keys bouce right back when you hit them. Very well built. Designed for extended use to be easy on the wrists. Great product !!!

This wireless combo is a very good product. It looks good, and it feels even better when you use it. it is also quiet. The combo can connect to 3 different sources, and it can easily switch between them just by pressing 3 dedicated keys on the keyboard and the mouse. This I like it.

The keyboard is amazing. However, the mouse has flaws. The scroll button feels incredibly weak. And a time it doesn't wanna activate but the feature switching between PCs is amazing. You have up to three macros you can choose from. It's a lot cheaper than using a KMV switch. Overall, the quality is great however I wish it was like a standard keyboard so I could swap out keys so bad points are the keys being able to swap out and the mouse has weak and finicky scrolling wheel other than that highly recommend this keyboard and mouse

I found a great keyboard for a great price, but the keyboard that I got was used. It was rewrapped and not very well. The keyboard it self looked used with scuff marks and some dirt on the bottom. The battery in the mouse were dead, and keyboard batteries were not new but it worked. I did not return the keyboard because it works after putting in new batteries and it was at a great price. I'm still testing the unit to see how it works and if I am going to have any problems. The bottom of keyboard and mouse looks very used please see pictures.

unit will be returned 2/14 keyboard is Spanish instead of English ????? will purhase a mk540 to replace it.

Opened the box to a used keyboard with dirt prints, food and markings. All evidence of a used keyboard.

There was no usb dongle in the package! So I had to use bluetooth as the connection. Using bluetooth is very herky-jerky (technical term). The mouse and keyboard delay is so annoying. I don't recommend.
