Customer Ratings & Reviews

I went looking for a better keyboard for my everyday work computer and liked the feel of these keys. I also like the slight curve to the keyboard. Unlike some of the more extreme curved keyboards that twist my wrists too far, this one is just right! I didn't buy it for its ability to connect to Bluetooth devices but it turns out this has been a great feature. I use the regular dongle on my work computer and can connect to my Raspberry Pi project board with the push of a button. Same with the mouse , just pushing the button lets you control one item via the dongle and two other devices through Bluetooth. Great product, great design..

Keyboard is working flawlessly as expected. Comfortable to use.

I was tired of having to use different keyboards and mice to ontrol different computers, and since I had the monitor situation squared away, this combination seemed to fit my needs. The keyboard fits very nicely on my Standing Desk, and with big fingers, I needed the full size keyboard. The down side is that when switching from one computer to the other, it takes a couple of seconds for the computer to respond, but I am getting used to that. All in all, I love this setup, and highly recommend it!

This keyboard-mouse combo is so good that I compelled myself to write this positive review. This is by far one of the best I have used. I have a Mac and Windows and I keep switching my displays between mac and Windows and this fits works exactly as anticipated. I cant imagine any other product doing it in the market. And, most importantly, the switch is just a button press. I never thought my home office becomes this productive and saves desk space. Great Product..

The price was less than I expected. the ergonomic keyboard is actually lost on me because I'm not a "Touch" typist. the mouse has much more function than this amateur can imagine using and the most surprising feature is that that you can INSTANTLY change to each of 3 different devices.

Both keyboard and mouse are good quality. Keyboard wrist pad is nice and soft while still providing solid support. The mouse has nice accessory buttons with a solid click to them, so I have not had any issues with accidental clicks. Swapping between devices has been flawless so far. Seems to swap in 1-2 seconds as far as I can tell. Would definitely purchase again.

This excellent keyboard/mouse combo replaced an expensive brand name keyboard and mouse. I wish I'd known about the Logitech MK850 combo when I bought my previous combo about six months ago. I certainly would purchase this combination again and recommend it to anyone.

I use Mac, Windows, and Linux at my desk every day, with Mac being my preferred system. This has worked perfectly for that. They keyboard has been described as "mushy" in other reviews. I don't disagree, but I adapted pretty quickly. I would rather it feel a little mushy than have less travel, so that's fine. I do like that it's quiet, which is listed as a feature. It is certainly not clicky, which is fine for me. The mouse works well and feels good in my hand. I like being able to customize the buttons so that I can hold the side button and move the mouse to imitate trackpad gestures from my Mac. Now, for the annoyances. The keyboard is "quiet", but the mouse surprisingly is not. It's very clicky. I wish they were either both clicky or both quiet. As it is, it's a bit weird. Then, I've struggled to find a way to get them both to change to the new device when I push the 1, 2, or 3. Instead, I have to switch them both. It takes a half-second, but when I forget and start typing or moving the mouse without having switched both devices over it's a bit frustrating. I've gotten better at remembering, but this should be more intuitive. I wish there were more options for Mac-first multi-device keyboards like this, but there aren't. So I am satisfied at least that Logitech has attempted to fill the niche. It might not be the best, but it's good enough and fits my needs better than any other. The simple fact I'm able to use it with all three systems without unplugging any dongles or having multiple keyboards/mice on my desk has been a huge plus.

At first I was not happy when I could not get the flow function to work since this was the main reason I purchased this mouse / keyboard combo, but after further digging it was my anti-virus software and windows firewall that was preventing the flow from working. Now that it is working correctly I love it. The keys are a little tight but the mouse is very comfortable. Also the transition from pc to pc is pretty quick. Love the copy paste feature from one pc to another. I would give it more stars but from the other on line reviews the flow issue seems to be a big issue. If Logitech would give some guidance on this issue instead of me having to search on line forums for an hour to get flow to work it would be a 4-5 star review. So bottom line if you buy this product be sure to give Logitech flow all the proper permissions in all anti-virus software....UPDATE VPN also seems to cause issues with flow.

Love the ergonomic design and how smooth the keyboard and mouse are. The battery life has been great and the mouse’s navigation buttons are so useful

This keyboard/mouse combo replaces an earlier model keyboard/mouse combo, that served me well for nearly 15 years or so. Mouse still worked perfectly, but the painted on letters and numbers most frequently used on the keyboard had worn away. That was not too big a deal, because I am a touch typist, but it was annoying. Worst was that some of the most frequently keys were becoming unreliable; they took 2 or more hits to actually register. Also, these same keys and a few others tended to bind on the down stroke, if I did not have my fingers accurately placed on the keys. I could work around this, but it was always a distraction from my workflow. But, because of the longevity and prior reliability of the first kbd/mouse combo, I expect the same from the new one! This has some minor feature improvements, but it is otherwise identical in size and layout as my old keyboard.

I have two of these, one for Mac and one for PC. I like the keyboard, big clicky keys are fine with me, have to use two keys to work the volume, not the best. The mouse sucks on both the Mac and PC. Mouse has this side button that I can't program on the PC and reduces all the windows on the slightest touch, software to shut it off does not save (on any of the buttons). Works fine on the Mac, saves everything. Mac mouse has a on and off lag and tracking problem, replaced with a wire mouse, works great now, tracks great on the PC though. Logitech never should have put this on the market, I think it's too late to return these. I have to buy another mouse for my PC, or disable the side switch then I'll be OK. Really ruined my big sale price! I would recommend another model.

This is a terrific keyboard and mouse combo. It has a nice and good hand placement. Easily connects by Bluetooth with no connection issues and great battery life.

I like that I can use it for laptop and ipad. There's a little lag when it starts but don't mind. Personal settings are available with Logitech app. Battery check is also possible. No need to worry about losing/breaking usb receiver (but there's one if you prefer that).

Great keyboard and mouse combo. The keys have a nice resistance and the mouse feels great ergonomically.

The keyboard and mouse work well. Both items easily change between my 3 devices, but as far as I can tell it requires two of the devices to connect via bluetooth instead of the universal dongle by Logitech. The mouse scroll wheel has two settings—infinite scroll and normal scroll. I wish the infinite scroll was slightly less infinite, but it is a nice feature in case I’m browsing very large documents. The price is a little bit high, but what isn’t expensive these days, eh?

If you own a mac and need a keyboard and mouse combo, the Logitech MK850 Performance Wireless Keyboard and Optical Mouse are it. It's worth the extra money. The mouse is amazing and the keyboard is ergonomic.

So happy with this product, it is perfect for my home office. I loved it so much that I bought another set for my actual office.

The value and quality of the keyboard and mouse was outstanding. Very pleased with the purchase.

This is a great purchase for work. Quiet and nice!
