Customer Ratings & Reviews

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.

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.

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 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!

Great layout. Comfort lay out of keyboard curved is very good

It is an alright keyboard. I like how the keys feel, and I like the Bluetooth on it. What I don't like about it is how it doesn't come with a USB extender type thing so I can have the dongle closer to my keyboard, and I wish that the feet would be a lot stronger because after a few days of use one of the extendable feet had a piece snap off and one side is holding it in. I will most likely glue it in, but it is still annoying.

Using Bluetooth: 1 star Using 2 Unifying receivers (no BT): 5 stars (even though I miss having an ergo keyboard layout). I often work from home, and was looking for a keyboard/mouse combo that could be shared (and switched frequently) between 2 laptops running Windows. Both of my laptops, both monitors, the keyboard and mouse are within a few feet of each other. So, the close proximity may be causing some of my problems. But, it also seems like a typical setup for someone that works from home. (minor) Problem #1: I'm used to using Microsoft Ergo 4000 Keyboard, and really miss that layout, and key spacing. Problem #2: Originally, I set up one laptop with the included Unifying receiver, and the other laptop with Bluetooth. That setup was terrible because the BT connections frequently got dropped. At one point, I switched which laptop was using BT connections to see if that would resolve the problem, but I had the same frequent drops. The good news...my old mouse was a Logitech M705, and I was able to connect using that Unifying receiver instead of Bluetooth (after following directions found in a Logitech forum, including installing Logitech Unifying Software).

Love it so easy to hook up and comfortable. Would recommend

works flawlessly. no problems at all to date. well satisfied.

Its a nice keyboard overall. I own several different logitech models. This one uses regular batteries. I am curious to see how long they last. How the keys feel to the touch is subjective. For myself, I like a soft touch with s shallow key depression. This keyboard has a soft touch but a deeper plunge for the keys.

Great product, appreciate the soft very responsive keys
