    Great thought, horrible execution - key spacing

    First, keyboardists ... that is those who can touch type 95% of their keys, will probably find this keyboard as I did .. frustrating. The good? Logitech did the full inverted T for the cursors, and gave room above that for the standard 6 key horizontal layout of del/ins, home/end, and pgup / pgdwn. Where they failed however, is in key to key spacing across the keyboard. Its like typing on an uncomfortable laptop keyboard, where everything is jammed tightly and causes your WPM to drop because you have to keep going back to correct what you've typed for having miss-typed or inadvertently hit caps lock vs shift or tab as you intended. Because the keyboard was designed to be universal (mac is like what .. 5% or LESS of the market) between PC & MAC it includes the CMD key, a FN key (stupidly on both sides with one smaller on the left and one biggin' on the right) and this makes it *NOT* the keyboard you want it to be. Love the idea of getting 3 dongles to cycle not only my mouse and my keyboard to 3 machines (desktop & 2 laptops) via dongle or bluetooth ... but the keyboard is so uncomfortable to type on for someone that's been using computer keyboards for the better part of 30 years and before using selectric typewriters ... I'm constantly frustrated by such products that take one great step forward, but then perform a complete design stupidity by not just biting the bullet and making two different keyboards. The function key is really not needed at all .. how many people have really looked at their F keys and gotten to know how each keyboard maps different functions there, just like keyboards with dedicated volume and back/home keys for browsers. Its the design to placate idiots that really should just do, verses fit form and functionality. And if it really needed to include one, then having a smaller one on the right side only .. would have been the way to go .. but no... design idiots at Logitech just had to try to be ambidextrous and screw the lot of us. Sadly, though I'd really love to have a keyboard that does 3 PC's or 3 Mac's or combination of the like, this will not work for how tight the alphabetic keys are, and forcing people to type on a smaller than standard size layout. If you're serious about your typing skill and speed, this will *not* be the keyboard for you.

    Versatile, with a couple of annoyances.

    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.

    Utter garbage - massive Bluetooth issues.

    Like many of the other reviewers here I have been a loyal Logitech customer for many years... probably 15 in fact. When I saw this keyboard and mouse combo I was impressed. I needed something to easily switch between machines. Sadly, this keyboard and mouse and complete utter garbage. Out of the box, the unifying the connector worked immediately. But pairing to Bluetooth to two different Windows 10 machines was next to impossible. The first computer (a Dell Lattitude E5570 running Windows 10) took several attempts to get it to pair. It would find both the keyboard and mouse easily enough and would ask you to type a code into the keyboard to pair. And then it would pair. But then the light would go to a slow steady blink, which according to support means it is reconnecting. Out of about the 30-times I pressed the button to activate it, it would do the slow steady blink 29 of those 30 times. Only 1 time did the light go solid and I was able to use the keyboard over Bluetooth. For the second custom built gaming rig, I have an Intel Bluetooth card (that is about as vanilla and compatible as you can get with Bluetooth). It would always detect the mouse and keyboard and when you tried to pair it would report as connecting and then always fail and say to "try again". After messing with this thing for 1 hour I put it back in the box and sent it back. I wish I would have taken heed of all the other negative reviews that have mentioned massive connectivity issues with the Bluetooth. The keyboard and mouse were nice to use over the standard USB unifying connector. Just a shame the Bluetooth feature of this keyboard (its main selling point) is absolutely worthless.

    Love the feel of this keyboard - except two things

    I love a lot about this keyboard. Great tactile feel and slight curve is enough to help you type faster - but not so much that it is hard to switch back and forth with regular flat keyboards. This keyboard would be perfect - except for two major things for me. First, the back space button is too small and too close to keys next to it - so it is easy to accidentally miss it when typing fast. Second - for a windows user - the lower keys left of the space bar are normally Ctrl, Start, Alt. And the “Start” key normally has a window image on it - having the four keys instead of three there along with not having the normal windows images makes it so I have to pause to think before I hit one of those keys. For me these two thing mess up what would otherwise be a perfect keyboard. I understand they want to make one size fits all for Mac and Windows users (and I have a Mac as well) - but you want a keyboard to be intuitive and this is the wrong place to make something multifunctional - they should just make two versions of the keyboard. It would not be so disappointing, but I otherwise love this keyboard so have been trying to use it - but it drives me nuts every time I hit a wrong key. I have been in software for 25 years - use the internet all the time and this is the first post I have ever made that was not solicited by a local vendor looking to help themselves market. I say that hoping Logitech will read this and fix the keyboard. If they do - I will buy another and give it 5 stars.

    Great Concept, needs to go back to the lab!

    This is an awesome concept but execution is in betta stage at best! In short, if you decide to purchase this product, know that you are only buying the concept because the technology in this device is not there yet! So as long as you are fine with PAYING over $100 to deal with glitchy technology and aweful customer service then I say go for it! As for me, I’m returning this puppy tomorrow! Logitech has gotten really sloppy with their products over the last couple of years. I have purchasd several Logitech products in the past (3+ years) and have always been very pleased with the quality and reliable of their technology, Logitech was a name you could trust. However, in recent years (2 yrs give or take a year) I have noticed a significant downward shift. The quality of their products have taken a dive while their prices continue to rise. Logitech Customer Service has never been great, actually pretty darn bad but this was not a big issue because the products worked, well that is no longer the story. To be more specific about my experience, I tried using the toggle with my Macbook Pro. The mouse was glitchy, not showing up on the monitor and I’d have to keep wiggling it to make it come back online. When I paired the keyboard to my iPhone. That function worked as expected but when I tried to switch back to typing on the computer, the keyboard would not pair...yet the mouse worked. I recommend Logitech send this fabulous, CONCEPT ONLY, back to the lab and refuse to release it until it represents the quality standards your company was initially founded on.

    Workaround for BAD Lenovo Laptop keyboard

    I got this keyboard as a necessary workaround for my Lenovo laptop that I purchased Nov. 2016. I unfortunately sustained a major physical accident shortly after this purchase and did not use the laptop until about 5 months later. To my dismay I discovered the WORST laptop keyboard EVER! The Right shift key was divided into an [up cursor and shift ]. Even if this configuration had the up cursor to the Right, it would be better but it is on the left. As a female with smaller hands, I cannot easily reach beyond the cursor--it sends the cursor wildly up on documents. When I checked with BestBuy about trying to deal with this problem, they informed me that due to the passage of time, I could not return the computer. So I am STUCK with a laptop that I need to carry a full keyboard in order to word process successfully. :( I attached a felt dot in an attempt to work with the keyboard; it did not help.

    Bluetooth pairing inconsistent after a month

    I really love this keyboard. It's wireless, and can switch between three devices. I have it paired to my work laptop and personal laptop. I like the slanted area to rest your wrists. Overall it's very comfortable. I've had it for a little over a month and it's been working amazing until the last couple of days. Today alone, I've had to unpair and re-pair the keyboard with my laptop four times. For some reason the connectivity with my Windows 10 laptop is starting to act up. I was in the middle of writing email and it disconnected from my computer. Nothing in regards to my computer has changed; the laptop is the same, I haven't had any updates done to the system. The keyboard is disconnecting at random times. I'm very frustrated as I'm now past my 30 day return period back to Best Buy, and I'm constantly being forced to go into my settings and re-pair the device to my laptop. What's the point of getting a wireless keyboard if it can't stay connected. A waste of money, please look elsewhere.

    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).

    Almost excellent - Except for the ZERO button

    I type fast with minimal errors. I've seen other reviewers complaining they can't type fast on this keyboard because of the soft feeling of the keys. I beg to differ. If you have fast muscular lift in your fingers when you are typing, you will love it. If you depend on chunking down on every key stroke and getting heavy spring loaded rebound from the keyboard, you won't get it. I've had a lot of keyboards and this is my favorite feeling so far. Connects right up with my iPad too. Does NOT connect to my 2009 MBPRO via bluetooth. Not a big issue for me because if I were in a pinch, it still comes with the usb wireless adapter. MOST NEGATIVE FEEDBACK is that the ZERO button in the 10-key side of the keyboard does not register a keystroke unless you hit it on the right side of the key. I made several errors before repositioning my thumb to grab the zero more to the right which is not normal for me. I hit the ZERO with full force on the left side of the key and it will NOT register the keystoke. Could be a mfg defect.

    Seamless switch between Ubuntu and Windows 10

    At work I use a ubuntu machine and a windows machine, which required two separate keyboards and mice -- one set was wired, which was extra terrible. I read some reviews and decided to give this product a try, even though Logitech doesn't explicitly support Linux anymore. I am happy to report that this product immediately worked on both machines. I use the dongle in Linux and bluetooth to connect to Windows. I was also concerned that there would be lag or some typing would be lost over the bluetooth connection (as indicated by other reviews of this product). However, this has not been an issue at all. Using the mouse and keyboard smartswitch selectors I am able to switch between machines in less than a second and there is no loss of typing over the bluetooth. TL;DR: this product works exactly as I had hoped, and freed up a lot of desk space and ugly cords. 10/10 would recommend.

    Easy setup, Unacceptable Tech support

    Comfortable keyboard and mouse. Installation was easy with simple instructions. Unfortunately the keyboard stopped working after five weeks. The Logitech website was difficult to navigate to find the actual troubleshooting instructions. Tended to direct me to pages that told me all about the product but nothing on how to fix it. Once I stumbled upon the troubleshooting instructions they proved no help - one of their step instructions was to change the batteries and then turn the keyboard "ON" before proceeding to the next step. There is NO obvious "on" switch anywhere on the keyboard so I tried to find the on-line manual showing all the keyboard features - There is no manual. Tried their customer chat line - Waited for nearly a half hour to get through the 15 people ahead of me. When my turn came I got the notice "Connecting...." and waited and waited and waited. Finally after 10-15 minutes I hung up. All I wanted to know is where the heck is the "ON" switch or Key to turn the thing on!

    Keyboard is excellent. Mouse is too loud

    I love the quiet keys, the ergonomic shape of the keyboard with rest pad, and the three quick switch device buttons . While it has the function + calculator shortcut keys, I wish it had the dedicated calculator key like other Logitech keyboards. Also the three quick switch device buttons should blend better with the keyboard instead of being white. A light gray would be nice so the key are not so obnoxiously obvious. I am a fan of beautiful functional tech gear. Quick switch device keys place are in a great spot on the keyboard - easy to reach but out of the way. The mouse is full of features and I love the quick switch device button sits on top of the mouse where it is easily accessible. The click is just too loud especially being paired with the really quiet keyboard. This is a great set. It would be a perfect set if it the keyboard was paired with Logitech's MX Master Mouse which has a quieter click or the keyboard could be purchased separately. Definitely worth buying.

    Many Problems

    • My Best Buy® Elite MemberElite Member

    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.

    The keyboard and mouse is good overall. It has this weird thing where a real mouse has to be plugged in for it to operate like it should. Sort of defeats the purpose. The other issue is the switching between computers does not seem to work as flawlessly as advertised. I set it up on a work laptop and gaming computer and it will work for a day, maybe two, and then the work computer wont recognize the keyboard and mouse all together. I tried the little dogle thing, same thing happened. I finally gave up on the switching (main reason I got it). BUt the keyboard is comfortable, so I kept it for gaming. I also expierence no notable lag between input and action on the computer, which I have expereinced with other keyboards and mice during gaming. So two pluses. But did not really do one of the main things it advertises, so I would not recommend the extra money over a lower model.

    Wireless keyboard & mouse

    I replaced my wired keyboard and mouse that have been a problem for years with too short of cords with my first wireless keyboard. The keyboard is responsive and clear feel and responsive Both the mouse and keyboard have three easy to switch setups to use on different systems. The mouse fits nice to my hand and is responsive to small changes. The prices were competitive and the quality excellent. My only negative is that my prior keyboard had dedicated buttons for speaker on/off/volume. That is available on another wireless Logitech keyboard/mouse combo and I did not realize how much I used it when I selected between the two. After over a month of daily use I am very satisfied with my Logitech products and would buy again.

    I am so tired of the uncomfortable "chicklet" style keyboards for the Mac. Even the Logitech K750 solar keyboard for the Mac is uncomfortable to me. Plus, I've had problems with that one in the past. This one is perfect. The keys are nice and comfortable with a decent keystroke. The keys are soft (I do not like mechanical keyboards). It works flawlessly with my iMac 27", with only the DVD eject button not accounted for (not a problem, since I don't have a DVD player on the computer). I can type much faster and easier now. No problems with pairing via Bluetooth, and only a small delay when bringing the computer out of sleep mode (no different from what I experience with my Apple keyboard). I'm quite happy with this purchase.

    This combo has been great for minimalizing peripheral clutter on my work desk. I work both on mac and pc, so I needed a device that allowed me to switch back and forth without having to move keyboards and mice around. This combo fit the bill. Push 1 button on the keyboard and 1 on the mouse and like magic, I'm swapped to the other device. Even better is the Logitech flow software that allows me to transfer files between devices. Sounds impossible but it actually works. The only thing I can think to make my setup even better would be to dual OS my pc with a little Hackintosh magic, but what good would the Logitech flow software be at that point.

    Keyboard purchased from bestbuy.com was defective (space bar did not work). Called Logitech and they agreed to send me a replacement. After 14 days I had not yet received the replacement. Called them and learned that they had not finished processing the replacement order. Then 10 days later, I received the replacement. The space bar worked fine, but all the words on the keys were in some foreign language. I returned it to Logitech. Eight days later I finally received a working keyboard from Logitech. The whole process took some 30 days.

    I purchased this Keyboard and Mouse set to replace my Microsoft Wireless Comfort Keyboard 5050. The keys are very comfortable to the touch and have just the right "feel". The hand rest is comfortable and as I design Apps. for ANDROID, I typically spend MANY hours typing and this keyboard is less fatiguing than a standard board. I prefer my Microsoft 5050 but, I am not 100% used to this Logitech-MK850 board. The Optical Mouse is designed for the right hand, but I have had no issues using my left. Tracking is good and the distance (with included Range Extender) is AMAZING! Overall, even though (my opinion) the MK850 is a bit pricey, I would not only purchase it again to give as a Christmas gift, I would highly recommend it as well.

    So this keyboard ergonomically is great. BUT if you are buying this keyboard and expect customization you will be left wanting. if you want to use the f keys for crtl / alt functions or any other functions then the 6 or so you can customize it wont work. so the keyboard is not compatible with any use like command line interfaces, text editors, or linux, the oversimplified software makes it worse . the sound managements function keys stick as well so at random intervals you will have no sound or ear shattering maxed out speakers, which is only fixed by plugging and unplugging the usb reciever. the sound issue may be isolated to my own purchase but who knows. logictech, one of my favorite affordable companies may have dropped the ball on this one.
