Customer Ratings & Reviews

The keyboard has been great for daily use at work. I have had no issues with it. It can connect via Bluetooth or USB drive so it is very convenient. I struggled a bit when connecting via Bluetooth but that's all. Mouse feels great in my hand and the slight curve to the keyboard provides some ergonomic relief.

I like the way this keyboard feels. Not loud and fingers lay comfortably, for me, across the keys. Both mouse and keyboard are responsive and the Bluetooth set up was easy. I am not a fan of the usual laptop input devices and this product is the perfect fix. Also no dongle to lose. Yay! Bonus. I have at least three of those laying around that I have no idea what devices they go to. If you want ease of use and set up I would suggest this product.

I am extremely happy with the Logitech MK850 Performance Keyboard and Mouse Combo. The keyboard is very comfortable to type on, with smooth keys and a solid, full-size layout that makes long work sessions easier. The cushioned palm rest is a big plus for comfort. The mouse glides well, feels great in the hand, and the ability to switch between devices is incredibly convenient. Both the keyboard and mouse have strong wireless connectivity with no lag or interruptions. Setup was fast and seamless on both my PC and Mac. Overall, the quality, comfort, and reliability of this combo make it a great investment. Highly recommended!

I searched high and low for a keyboard that was ergonomic with keys far enough apart and elevated. This keyboard is also bluetooth and you can connect it to 3 screens. It also comes with a wireless ergonomic mouse. I love it!

Let me start by saying, I’m kind of a Logitech snob! I have two Joysticks, a MoMo Steering wheel & two sets of 5.1 speakers! My old Logitech Optical Keyboard and Mouse combo finally died, may it rest in peace! It had served me well for almost 20 years, that say’s a lot of the quality of Logitech products! So naturally, I went to my local Best Buy to check out the latest Keyboard and Mouse combo sets. Let me first say, I’m a person who likes to try on my shoes before I buy, so after testing the feel & feedback of all the keyboards keys & mice, I purchased the Logitech - MK850 Performance Full-size Wireless Optical Keyboard and Mouse combo, in black. I like the way the keyboard is weighed, it has a well built feel to it. The mouse has a good contour that feels just right in my hand. The buttons are crisp and work well. I really like the On/Off switch on the mouse, my older Logitech Keyboard & Mouse combo didn’t have that, that’s how old it was! I noticed that the keyboard has an auto shut off feature. I didn’t see it until I went into the software to set it up that it did that, nice touch! Speaking of which, the software auto download’s and is easy to use. The set-up was a snap and the Logitech MK850 Keyboard & Mouse combo worked right out of the box, no issues. I have two P.C.’s on my desk, so I purchased a second Logitech - USB Unifying Receiver. The keyboard & mouse have corresponding numbers on them to indicate which device is active, so you would think it would be “brain dead dumb” to set-up, right? Not quite! Here’s where the only issue I have with this Logitech MK850 Keyboard & Mouse combo comes up. First the software has to be installed on both P.C.’s before you can set the Keyboard & Mouse combo to the number you want (It defaults to number one) The instructions are really vague on this. The mouse worked correctly, just read the instructions, the keyboard was another story. The instructions tell you to turn off the mouse and then turn it back on to assign it the corresponding number (1,2 or 3) No problem, these are on the mouse & keyboard. That worked fine, the keyboard doesn’t have an off switch, so you have to remove one of the batteries! Then put it back in, and then assign it the number you want it to be. The instructions make no mention of this! After having & using the Logitech MK850 Performance Full-size Wireless Optical Keyboard and Mouse combo for two month’s I have to say I love this set-up. I highly recommend this keyboard & mouse combo, I’m sure it will serve me well for another 20 years!

This keyboard and mouse combo works like a champ with multi-computer feature allows you to control multiple devices and switch seamlessly.

The mouse click pretty loudly, so I bought another one, but the keyboard is AMAZING! I take it with me in my backpack for working a the library and at home. It connects to my computer quickly. The sound of the keys is very pleasant - not too loud but still a good sound. The wrist rest is also very comfortable and helps me work on different surfaces more easily.

I prefer using the wireless keyboard instead of typing directly on my laptop because I find that I can work faster since it's the same size keyboard that I use in the office, so I'm used to that. I also like the clicking noise that the keys make. The wrist pad however, is made of some kind of fabric which isn't detachable, so I cover it with a paper towel to keep it from getting soiled. The mouse works great, but a slighly annoying feature is pressing your thumb on the side accidently thumbnails what you're looking at. The set was a little confusing to set up but you can control several devices with it once you get it up and running. Batteries last a long long time.

I had to get a replacement for my previous LOGITECH MK850 KEYBOARD because I dropped soda on it and the keys began to stick. Anyway, there are cheaper and smaller options as far as keyboards are concerned, but I like the MK850. I can use the USB transmitter for both the keyboard and the mouse for wireless connectivity, and the keyboard also has Bluetooth, so I can connect it to my TV. The MK850 has a full numerical keypad, function keys, palm rest, and you can program 3 additional devices on it (I've got my iPhone and iPad) with their own dedicated selection buttons (the 3 white buttons on the keyboard), and the keys have a good tactile feel to them that's not loud or strong when you press a key, so you get some feedback. I would've preferred a stronger feedback from the keys because it helps me keep a rhythm going when typing, but at least it has something. Both the mouse and keyboard have on/off switch and the mouse takes 1AA battery and the keyboard takes 2 AAA batteries, which are included.

I buy keyboards and mice for a business, and only use Logitech that have the Unifying Receiver, so that I can replace any bad devices and pair the existing receiver with the replacement device. It keeps us from filling up USB ports with multiple receivers. And it's more reliable than Bluetooth. Also, the quality of the keyboards and mice are top notch.

I got this set to have for working from home. So far i have been using them for 2 months and they work really really well. They link via bluetooth seamlessly and effectively. They link with multiple devices and have not had any issues switching between the linked devices. Battery has not moved off 100% yet and its been 8 hrs a day 5-7 days a week! Would definitely recommend to anyone looking for a comfortable keyboard and mouse with many customizable buttons and effects. 10/10!

Great product. The mouse works smoothly and the keyboard types easy. It also has a long battery life.

This has been an excellent product to use! Long lasting on battery (as long as you remember to turn it off after use.) The feel of the keyboard is comfortable and the mouse feels sturdy. Quickly connects to my computer without any problems. Would definitely purchase again!

Plug and play, not to heavy if using on lap. Quiet and smooth clicking.

I bought this keyboard / mouse set as a replacement for another MK-850 that lasted for years, but was dying. I haven't seen anything on the market close to this comfort and functionality. I absolutely needed one wireless keyboard that I could use for multiple computers for my workstation. Setup is very easy and once connected it's fast and responsive. The only "misses" are sometimes there's a bit of a lag connecting to my Mac (maybe it's the Mac? I don't know) and on my Windows PC sometimes the return key or random letters will "stick". But it doesn't happen very often. They're minor inconveniences and it's worth it!

Cons: A little bit of a lag on keyboard. Mouse has button on left side that might accidently click every now and then. \ Pros: The moue and keyboard have 3 saved devices so you can easily switch between computers. I use this in my macbook pro and pc laptop and switching between devices is super easy. The keyboard is comfortable and has legs for angle. The mouse works good and has a scroll that actually spins so you can scroll through hundreds of items at a time. So far batteries are still working that it came with after 3 weeks so not sure how long they last. Another plus is that there is no USB required you just connect via bluetooth so no more losing the USB plug or taking an extra space on computer. Overall I really like this Keyboard mouse combo.

I needed a device to connect to my work PC, my home PC, and my Surface Pro, all without having to disconnect anything, or go through any extensive software changes to make it happen. This does exactly that. While it offers bluetooth, I decided to purchase multiple Logitech Unifying receivers, as that is more reliable and faster to switch between devices. With the press of a button, you are now using each device on another computer. No need for a ton of wires for my old KVM switches or USB switches. The Keyboard Curvature took a couple days to get used to, but once I did, it feels great in my hands.

Works great both Bluetooth and with the usb the mouse I use every day with the customizable keys. They are life saving while working on civil engineering

Keyboard is very comfortable to type with, even though the keys are membrane its very easy to type on this keyboard due to the ergonomics. Keys are surprisingly quiet. The mouse compared to other wireless logitech mouses is very nice in the palm. Its larger than most traditional ones used for laptops and the ability to pair it with three separate devices is a plus. Overall i would rate this a 8/10. The only con I can think of is I have notice there is a slight latency, its not much but enough for me to notice as a gamer lol (this was used in an office environment) and its a little pricey especially for it being a membrane wireless keyboard.

This is a great keyboard to have if you are using a work computer and you personal computer or even using this keyboard to play on your PS or Xbox. Barely in lag in connecting to the device. Easy setup.
