I recently purchased a couple of Mini PC's to handle a number of tasks both for business and personal uses which are amazing little machines, however, soon after I got them I realized that I had not taken into account the frustrations of having to connect and disconnect my old USB keyboard! At first I was just going to purchase a regular Logitech Keyboard with a Unify dongle as I have always been pleased with them in the mice I have. But then I realized I would still have to connect and disconnect the Unify Dongle to each PC as well. So I started looking for Bluetooth keyboards because they would be much easier to switch between. That was until doing some searching and found that they had a few keyboards which could support multiple devices via Bluetooth! I purchased this one as it was one of the few which was priced where I could afford it and even better it was a full size keyboard with a number pad.

As soon as I received it I unboxed it and took the battery cover off to take the little plastic tab (battery saver) from between the 2 AAA batteries which are included, so I could get to trying it out. To my surprise it was NOT just Bluetooth but it also came with a Unify Adapter! Now that was a pleasant surprise because at the time, one of my MiniPC's which sadly I had to return because of many issues (be careful buying refurbs) did not have Bluetooth, so I thought I would have to purchase a Bluetooth adapter for it, but with this keyboard coming with the Unify Dongle, it allows me to connect this keyboard to 3 Bluetooth PC's and use the Unify Adapter for everything else! I was not expecting the Unify Dongle and perhaps I did not read the description very well, but I don't recall it mentioning that,

I have now been using the keyboard for a bit and setting it up with the 3 MiniPc's was a piece of cake, very simple and had no issues at all. It easily switches between each device with the touch of a button, and takes a couple of seconds to reconnect (only need to pair once). One really nice feature is that after a couple minutes of no use, the keyboard will go into battery save mode, then when your ready to type again, only takes but 1-2 seconds to start typing again. While some might think that would be a hassle, when you consider how much battery this will save, it's easily over looked. The manufacture Logitech states that they batteries should last 2 years in one of their other Bluetooth keyboards which I also purchased for my other misc devices, so I would have to imagine that using Bluetooth alone and not the Unify adapter, I should get similar results from this, but only time will tell. Though I am only using the batteries that it came with right now, and who knows how long they have been sitting in the device before i purchased it and they are generic batteries. I am guessing I won't get that long, however, if I get a few months out of the 2 batteries which as much as I use it, I will be impressed none the less. When switching from PC to PC you simple hit the white button at the top that corresponds to the device that you pair the keyboard with and within 3 seconds, the keyboard is connected to that device and your ready to start typing away.

The only down side that I have found is that I can not find the one key that I use a lot, and I was unable to find it on the Logitech support site nor in the manual online for this keyboard, is the Print Screen button. It's usually on the right side top of most keyboards or in the number pad somewhere, but I can't find it. I looked on Google and couldn't find an answer their either so I will have to send an email to Logitech support to find out where it is, but again, this is a minor inconvenience for now, but at least I know there is an easy solution for that once they respond and let me know.

With a couple tiny inconveniences that are really low on my list of issues I have ever had with technology gadgets I have ever purchased, I am very happy with the purchase of this keyboard and I recommend this to anyone who needs a Bluetooth keyboard and needs the ability to connect to more then 1 device. It's incredibly well made, and had some weight to it, so you can tell it's not just some cheap piece of plastic keyboard, It has a nice no slip bottom which holds on to any surface you use it on, and it is constructed with an incredibly useful holder on the top which is where the white strip is which was designed to hold your portable devices like a mobile phone or tablet. Since I am not using it with those devices, I find it very useful for holding everything from pens and credit cards (perhaps I use that last one too much) to pieces of paper like a password list and even a notepad which I need to read from while working. It is a great keyboard and I am glad I choose this one over some of the other brands I was looking at and while it cost a little more then the others, Logitech is in my mind the absolute leader in mice and keyboards, and once again, they did not let me down! (PS- This keyboaard is a perfect match when purchased with their Multi Device (3 devices) M720 Bluetooth mouse which also comes with it's own Unify Dongle! Both paid via Bluetooth to 3 devices, and both have their own Unify Dongle. If you download Logitech's Unity app, you can actually pair both the keyboard and mouse to the same Unify adapter since each dongle can pair with up to 6 Unify capable devices. They are a match made in heaven!

I hope this helps someone who might be looking for this type of a solution because had I read a review from someone else about these, I would not have spent 3 days of endless searching, which ultimately, I am glad I did and got this pair!

This is hands down one of the best keyboards I've ever used.

First of all the packaging itself, I'm no fan boy of Logitech but the aesthetic from box to product is just on point and fantastic. Very modern minimalist feeling. It's like if this keyboard were a home, it'd be on Grand Designs...

Anyways set up is dead simple.

Follow the instructions on the box and you'll be fine, just remember to use the right process for either MacOS or Windows etc.

The keys have a very, very solid feel to them. They feel leaps and bounds better to me than the action you get on a macbook pro keyboard pre 2016 or the magic keyboard version 1. Just less squish and more satisfying.

Holy smokes they're quiet too, it's like the ninja of keyboards.

The circular keys were really easy to get used to, and to be frank they look so much nicer from an aesthetic point of view in my opinion. Very typewriter-esque.

Pairing with the unifying dongle was great because I also bought a Logitech MX Master mouse, it simply required I plug both dongles in at first.

Eventually the software (for the love of god just install Options, it's amazing) recognized I had two dongles and asked if I'd like to remove one from my mix. Easy to follow steps later and I was there.

There's a fair amount of travel for such a low profile keyboard on the keys, nothing crazy but enough to really feel like I got ish done when I finish banging out an email.

Most importantly, switching between machines that I control with this is a breeze. Once you're done pairing you literally just hit the button on the keyboard for the device you'd like to control and you're done.

I game on a PC and I work on a Macbook Pro 2016, and this thing does it all.

I high reccomend installing the options software, so you can remap the FN keys and change their behavior.

Are you one of those heathens that wants the FN keys to automatically require you hold FN to do volume up and down? There's a setting for that.

Do you want to map the home button on Windows 10 to TaskView (which I love)? Go for it, in Options.

You can even turn on application specific mapping of buttons and have the mappable buttons do different things depending on what app you're focused on at the moment. I've done this with Excel and a few games.

Lastly even if you don't want to use this to control a phone or tablet, the little tray is one of the coolest things ever, because you simply just "dock" your phone or tab there. I use it with my LG G6 and it's just superb.

Over all if you're thinking about getting this keyboard stop thinking and start doing.

Even if you don't have more than one device, and don't plan to use its switching capabilities, it's just a fantastic piece of kit that's really one of a kind and works really well.

This is long-term owner's review. I own this keyboard since 2018, when I bought it along with M720 mouse. I bought them specifically for multi-device functionality to switch between my personal and work laptops when working from home.

Keyboard itself takes some time to get adjusted to, after years of using more traditional, larger keyboards. For me, the hardest part was that arrows are right below Enter and Shift buttons - when writing text I often hit the area to the upper left side from arrows, where Enter supposed to be. Also, having F-keys as a secondary action that requires pressing Fn button is annoying sometimes, but I don't use those keys much.

I like the design of round keys, I find that key action is good enough and not worse than any compact keyboard. The phone/tablet stand was not useful a lot for me. I don't use tablets, though, and I imagine it's helpful to put a tablet into the stand if the tablet doesn't have it's own stand. Battery life was great. I think I had to change batteries once since 2018. Overall, I'm satisfied with this keyboard.

Now why I decided to write this review after 4 years using a keyboard? It kept well over the years, but the mouse I used with it got the soft cover material deteriorated. I wanted to replace the mouse with the same model, and keep the keyboard, and 2 USB dongles I was using with my laptops. Unfortunately, the new mouse came with C-U0008 USB receiver, and the old mouse and keyboard from 2018 had C-U0007. Now, despite that new mouse was exactly the same model as old one, and all those products advertised to be compatible with "unifying" receivers, they are not. Old K780 keyboard is not compatible with new C-U0008 USB receiver, and new M720 mouse doesn't work with old C-U0007 receiver. Logitech, this is a really bad way to s.... customers. There is a kind of a workaround - use Bluetooth instead of RF, but it doesn't connect instantly, there is a few seconds gap between the moment you press switch button and when the keys start working on another device. It's not much of a deal, but it's very annoying, especially as I have to use it because of Logitech's fault to keep the "unifying" receiver ecosystem really unifying. Also, this will not work for everyone - not all desktop PCs have Bluetooth.

Now I either have to live with laggy Bluetooth connection or buy a new keyboard with C-U0008 USB receiver to have my setup working again. Or I'd rather return the new M720 mouse and get Dell or some other brand making multi-device keyboards.

UPDATE: Changed 4 star to 5 stars because all compatibility complaints above are wrong. Unifying receiver works as it should, it's just not that straightforward to re-pair existing devices from old to new receivers. You need some kind of software that can trigger "unpairing" of device from old receiver so it can be paired again on the same channel with the new receiver. For Windows I used "Logitech Unifying Software" and for Linux I used "Solaar".

Wow! This is a truly well-designed product overall. I ordered the "white" version, meaning the bottom and device cradle are a white rubbery substance. The rest of the keyboard is a matte-black, which I definitely prefer over the glossy black that most devices come in.

Pros:

- the design is very sharp and modern looking. In fact, if you are a nut about design consistency like I am, Logitech also offers a set of speakers and a mouse with the same design scheme.

- tactile feel is great. I thought the rounded keys would take some getting used to, but the transition from a standard keyboard was seamless for me.

- weight - this keyboard has some heft. I view that as a positive, since it needs to be a little heavy to hold devices upright in the built-in stand. Just another thing to make it feel like a premium product.

- portability - while not necessary in my setup, the fact that this relies on either bluetooth or a usb dongle instead of wires makes it better in my book.

- this is a full keyboard, unlike its predecessor that did not contain a number pad.

- multi-device use - this is why I purchased this keyboard in the end. It has the ability to connect to up to 3 devices and switches between them at the push of a button. This was critical for me, since I wanted to control my dual-monitor setup with a desktop and laptop hooked up through a kvm switch. My switch was on the cheaper side, so it only has shared HDMI in/out, no shared USB. I didn't want to shell out hundreds of dollars for a single switch to cover my needs, so this fit the bill nicely. I didn't think I would even connect it to my phone, but I have found that to be an incredibly useful feature.

Con:

- the only con I can think of is that they replaced the F1-12 keys with the keys to switch between devices and other assorted commands. In order to use any F keys, you have to press FN first, which can get annoying. That probably isn't going to be an issue for most people, but it's a minor annoyance for me.

I wanted a change from my loud, high-travel mechanical keyboard which was becoming cumbersome for typing and a bit too loud for my setting. This Logitech K780 fulfilled all the requirements of a great keyboard. The keys have a nice tactile feel that lets you know when the key is pressed but is not loud or obnoxious. There is enough travel to distinguish a key activation but you can still move from one key to the other quickly. Some people might need some adjustment to the round keycaps but for me it wasn't an issue and feels perfectly natural. Although the keys are not backlit, I have no trouble reading them at my desk. The function keys work great with my Mac and iOS devices. All of the keyboard shortcuts for Photoshop, Illustrator, and other software work fine with the Mac-labeled keys. I would have liked to see a Caps Lock light to appear on the keyboard, but a quick box does appear on-screen to notify you of the change. The angle of the keyboard feels natural and has required no adjustment. Overall, the layout with the number pad has felt great and this keyboard provides a satisfying typing experience. It pairs well with my MX Master and is a great buy for someone looking for a keyboard with great style and functionality.

This is a great addition to an office requiring frequent interaction/communication on multiple devices. I was very pleased that I was able to overcome iMessage forwarding inconsistencies by using this keyboard as a workaround. I've paired 3 devices and being able to toggle between each using the touch keys is very convenient and fast. I'm able to send text messages very quickly by touching intermittently with a single hand vs. lifting my hands from my keyboard, holding the device and interrupting my workflow as was experienced previously. I purchased the white/black option and the matte finish is nice, the grips on the bottom keep it in place nicely, it is low-profile and I found the angle eliminated the need for a wrist support. The keys are round, but the placement is good and there were no ergonomic issues experienced. The keys are relatively quiet, but not silent unless you are typing quite slowly. The only drawback I have found is that your iPhone/iPad will only fit in the grooved area when uncovered. I was able to easily remove my phone protective cases, but if you are in and out of the office a lot, it might be a bit of a hassle to use this feature. Potentially adding a "slide out" option in future iterations will eliminate this problem, but for now you can also just use your own phone/device prop and most iPad cases feature an easel position for viewing too. I am a fan of Logitech generally, and this product line lives up to my expectations of this brand. This performs as advertised and I had no issues of compatibility and am able to use all function keys as displayed without any issue. Great product.

On occasion i buy a piece of technology which really impresses me. This is an impressive keyboard. I generally use high end keyboards which have a solid feel and mechanical keys. I was re configuring my home office and wanted to get a wireless keyboard. I saw this unit and it looked interesting . When i got it, i was more than impressed. I was amazed. It has a solid feel. It is real flat but the keys have a solid feel. It is completely quiet even with my heavy touch. I type very fast and there is almost zero noise. So i can take notes when talking with someone without them hearing it on the phone. If that was not all good enough, i can use it almost seamlessly with my iPad and iPhone. Works great with them also. It even has a slot to prop them up in front of you. I hooked this up with Blue Tooth connection which works flawlessly so far. Even better i did not have to disconnect my wired keyboard but could move it out of the way and use this keyboard. When i want to go back to my gamer keyboard i can slide it out and use it without having to reconnect it. I think the only time i would use the mechanical keyboard is when i play a video game that uses the keyboard. This is worth the money and an engineering feat.

This is one fine keyboard. For the last 15 years, I have shied away from buying products for Logitech, having found their drivers and accessory software to be quite flaky "back in the day." With my desktop's keyboard pretty well worn out, I was in the market for a replacement. Consulting The Wirecutter's reviews (a publication of The New York Times), this keyboard had a very high rating so I took a chance and ordered. I'm delighted. I do run this on Bluetooth rather than Logitech's proprietary wireless implementation and I did not install Logitech's accessory software (15-year old burns heal slowly). I love the tactile feel of the keys and I have noticed a significant increase in my typing speed and decrease in typo's. The keyboard stays firmly planted on my keyboard tray. The ergonomics feel perfect to me, and certainly easier on the wrists than the more traditional raised / sloping keyboards. It is effortless to switch between my Windows 10 desktop and my iPad. Once paired, Bluetooth connections hold and re-establish without intervention on computer start-up. The tray slot is just fine for my 9.7" iPad in either landscape or portrait mode. I highly recommend this keyboard for anyone needing connectivity to two or three BT devices. If you need to connect to only a single BT device, I believe Amazon carries a similar Logitech keyboard that is absent the multi-device capability.

I absolutely love this keyboard. Just to specify, the white version I got corresponds to the colour of the device holder attached to the keyboard. The speckled version would correspond to the device holder having a speckled appearance. I was happy to know that I received the plain white version as it is the one I had wanted. The device holder also has a soft-rubber texture which ensures it will not scratch your devices if you place them in without a case.

The keyboard has an adequate amount of weight to it so I would state that this would be more of a desktop keyboard rather than portable one. It is bigger than I expected, but no issues there. One of the features I enjoy is the fact it is NOT rechargeable. That means that there is no life-span on this keyboard since rechargeable items tend to lose their ability to hold charge overtime.

Typing-wise, the keyboard feels sturdy and it is not as loud as some keyboards can be. I’d equate the movement close to the old 2012 MacBook Pro laptops with the clicks feel. The rounded keys do not bother me much in terms of typing and it was easy to get used to. Pairing the device to my systems was fairly easy via Bluetooth. I enjoy the fact that this is a full keyboard with a number pad. The device stand is able to hold my iPad Air 3 at a great angle (even when I have a case on it). I cannot comment on battery life as I just got it, but i do plan to turn off the keyboard if I am not using it.

I mainly bought his keyboard as I plan to use it with my 1. iPad 2. My Windows computer 3. My 2012 MacBook Pro.

No complaints in terms of the experience, though I do wish there was an indicator to know when CAPS lock is turned on.

Other than that, i would recommend this keyboard.

Es un excelente teclado: se conecta y cambia de dispositivos muy rapidamente. Calidad de teclas excelente. La cabidad para que coloques tu dispositivo como tablet o cel es un poco angosta así que solo cabe si lo tienes sin funda

I wanted a full-sized Bluetooth keyboard to use with my Macbook Pro, since I use it as a second monitor and can't reach the keyboard. I'm a video editor and use a lot of keyboard shortcuts and software that makes use of the number pad, which is why I wanted the full size.

A couple months after getting this keyboard I'm super impressed with the quality and value. It sits flat, types well, and connects right out of the box. I've had it on constantly for two months (there's a simple on/off switch on the side) and I haven't had any issues with battery power. The keys are robust and have a good weight to them, and there are lots of handy shortcut buttons at the top. The keyboard is heavier than it looks, so I wouldn't recommend it for carrying around, but if you keep it on your desk the weight is actually a feature (it doesn't slide around when you type).

I'm no keyboard snob but this one was a wise investment.

equipamento de primeira qualidade. A troca de uso entre equipamentos funciona de primeira. Apenas duas informações para análise. O teclado tem o padrão americano, então para quem não tem muita prática para digitar pode trazer um pouco de desconforto. E tb sobre as teclas fn fica um pouco diferente o uso. Porx exemplo para atualizar uma página, tem que apertar o fn+f5. Tirando esses dois detalhes, o teclado para mim é perfeito.

Very good product, easy to use, just bought my second one. Worth to invest to increase your workability if multi devices operating is your goal.

Only two down sides for me are to use "page up & page down", you have to press "caps lock", and once it connected between a Mac and a Wins, to switch between two software, the switch function is sometime "F1", sometime "fn+F1" depends on either Mac or Wins you are one.

A very good part of this keyboard is, you can use logi flow software on it once you bought a mouse that has the flow availability.

Overall, I am using this every day, and it works so well.
