Customer Ratings & Reviews

Comfortable ergonomic keyboard with a good response. Few performance issues under Windows 21H1. I look forward to learning about the programmable keys!

The way of designing is perfectly. Hand dont get tured when i work.

The Logitech - MK850 Performance Full-size Wireless Optical Keyboard and Mouse really preforms when your connected to your favorite mobile device..

Was time for an upgrade. Love the Bluetooth connection. Really like that I can use it on multiple computers as well. Very convenient.

We needed a laptop to allow my wife to work from home during the COVID 19 situation - but we also needed the full size keyboard and mouse - this fit the ticket perfectly!Connected with ease!

My wrist does not hurt anymore. Its curve design allows for a comfortable wrist rest.

I liked the idea of this combination and the ability to switch between different computers/tablets. The switching works well but in practice it causes issues as it's frequently slow to wake up and misses key strokes which can be frustrating. I couldn't find a left handed mouse so the shape of the mouse isn't ideal but it's workable but not sure I would recommend to other lefties. Finally I am not a big fan of the fabric palm rest it seems that will get dirty over time and isn't particularly hygienic. Other than that it works fine and is worth considering if you want to switch between devices if not I would go with something else.

The mouse is great. And if you find a good refurb/open box deal, sometimes you can get the mouse for less than buying it alone. But the keyboard is terrible. Hard to believe it comes from the same company that makes the mx keys keyboard. Keys are kinda mushy, the keyboard is bulky and not very comfortable. True ergo keyboards like the MS Natural one - are fine - they are bulky but the bulk gives you the great comfort. Not the case here - it is just not great. I tried a few times (returned/exchanged) and each had different defects. Some would miss key presses / flaky blue tooth. Another connected just fine but the M key is hit or miss. Skip it - it isn't worth buying.

Decent for regular use on computers satisfied with what it is gets the job done

I bought this for the blue-tooth connectivity, It scared me at first when I saw the USB in the mouse, but after reading more I learned it can connect either way. Good product.

What a great package! Logitech can always be counted on to be an excellent product. And Best Buy stands behind its products.

An excellent product allowing the use on three different computers at the same time and gives you notification lights telling you where you stand; ie:cap lock and number lock etc.

I love this especially since it connects to the computer and phone.

I particularly like the feature whereby the keyboard can be used with 3 different devices. I can use it with my new. computer as well as my old laptop, I wish it were more ergonomic like my old Microsoft keyboard which I loved.

Great replacement keyboard and mouse if you need better performance and range. The style is nice and comfortable as well. Pairs easily without additional setup on most devices.

needed a keyboard that indicted if the cap-lock was on or was off; some of my websites give you 1 chance at your password before locking you out.

I have been using this setup for 2 weeks now and it has functioned as intended. I like the cushion for the wrist. And I love the option to quickly change to a different device whether through keyboard or mouse.

I love this keyboard / mouse combo so much I bought a second one. Being able to link the keyboard to three different computers / laptop / table / phone using the unifying USB adapter or Bluetooth makes it great.

Great product. Being wireless it can be used perfectly on multiple devices. Happy with the purchase

The Logitech wireless keyboard and mouse combination was, as usual for Logitech products, easy to set up and get operational.
