Logitech K780 Multi-Device Wireless Keyboard

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.

If you want a gaming keyboard, go mechanical, dive into switch types and that sort of thing. If you want a travel keyboard, go small, get a lightweight model that is easy to carry. If you want a keyboard for your HTPC, a keyboard for your heavy-use content-creator PC, or some other specific use case, this might not be the best choice. But if you are looking for a keyboard that will stay in one spot for everyday use with no exceptional requirements, this is the way to go. PROS: The build quality on this device is terrific. It feels solid. The switches and keys are firm, but buttery smooth. The texture is perfect. It's an all-around fantastic design. Setup is easy. You hold down one of the three pairing keys in the top left, wait for it to blink, then pair it with your phone, tablet, or PC like any other Bluetooth item. Simple as pie, no instructions needed. It just works. Batteries come in the device with a plastic pull tab to get it is started. No need to fumble around with opening the battery compartment, opening a pack of batteries, figuring out how to load them, etc. Just pull out the plastic tab and it's on. The channel up at the top is a great size for most devices. I have a Lenovo Miix 700 (basically a Surface Pro, but from Lenovo) that fits perfectly next to my OnePlus 5T up at the top. Even with both devices in there (and they are pretty heavy together), it feels like I would need to work pretty hard to get it to tip backwards or fall over. It's a heavy keyboard, with solid counter-weights that prevent it from being overcome by the weight of even a large tablet. The devices themselves fit snugly because the channel is lined with a slightly rubbery texture that holds tight. CONS (not really cons, just potential cons to be aware of): It has the standard Logitech sleep feature. This means it goes to sleep after like 30 secs of non-use. You'll get used to it, but it means when you go to type after a while of not typing, you have to hit the first key, wait for the letter to appear (maybe a second or two delay), then you can proceed with typing like normal. When it sleeps, it has to wake up, re-establish Bluetooth, and then send the data, so you can understand there is a slight delay. However, I've been using Logitech keyboards like this for years with that same behavior and it doesn't bother me. I know what to expect. It saves battery life, which is nice. It's heavy. This is both a feature and drawback. The feature here is that the extra weight acts as a counterbalance to anything you put in the top channel, like a phone or tablet. The drawback is that moving it and adjusting it requires a little extra effort. That is why I think this keyboard is really only good for someone that is going to keep it in the same spot all the time. It's not that it is too heavy to move, it's just too heavy to toss in a bag and take places all the time. CONCLUSION: This is a fantastic keyboard. If I was buying a Surface Pro or similar device and planning to use it in only a few different places, I would buy this keyboard (maybe even 2 or 3 of them and just leave them places) instead of the type cover. It's great.

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.

I'll get right to the point. I work with multiple computers both at home and at work. I hate all the clutter and was looking for something that was sleek and minimalist. I tried an off brand on amazon but to my disappointment while it was small and minimalist it felt plasticky and cheap. I came across the K780 and thought at first, it looked weird, what's with the stand or tray thing? I took a chance and ordered it anyway. From the moment I unboxed it I was happy. The feel of this keyboard, it has this rubberized matte velvety feel to it and the round keys are genius for those of us who actually know how to type QWERTY style this is an absolute must have. It's super quiet not clicky, they keys are springy and responsive. The round keys actually feel more natural and I actually make less mistakes. So I'm more productive and I fly through emails and Teams chats. The slim design doesn't eat up a lot of desk real estate and is perfectly positioned. Now about that white stand thingy...from the pics I was sure this could be removed. surely Logitech wouldn't attach something so obstrustive without giving you the option to remove it if you so chose. Nope, you can't take it off but then something strange happened, I got to work plugged the receiver into my desktop, paired it with my laptop, added my existing Logitech Track ball which had a Unity receiver, I had one more thing to pair...my Google Pixel 2XL paired perfectly and it fit into the tray like a glove. I had no idea how useful this would be. During the day when I want to check personal email, send a text, watch some Youtube at lunch at my desk, it sits in the stand while I have it plugged to the charger. It's fast responsive and the most perfect designed keyboard I've ever owned. I must have one for my home pc and I'm ordering a K380 for my son. This is by far the best keyboard I've ever owned. I have only one complaint but it is by far no deal break. The arrow keys are positioned in a funny place at the bottow of the keyboard and are actually very narrow, it's nothing too annoying it will just take some getting used to.

Having enjoyed the K380 for some time, I was excited to see this keyboard hit the market. I absolutely love the feel of the round keys and the semi-silent operation. I have average sized hands and the compact K380 has been very comfortable. Even so, it was nice to see the more widely spaced keys along with the tenkey. I'm keeping my K380 for writing on the go and replacing my everyday full keyboard with this one. I'm not a heavy user of function keys, so their dual functionality has not affected my experience. I do still have a bit of a learning curve ahead of me due to the displacement of the 'home' and 'end' keys. Instead of dedicated keys in the area they are expected to be, they appear as alternate keys in numbers 7 and 1 of the tenkey. The print screen function is also an alternate of the delete key. These along with the small arrow keys will surely take some getting used to. But I've faced larger challenges in life. These are minimal trade-offs for the excellent typing experience the K780 provides. Also, the ability to take the keyboard into another room to use with my iPad is hugely appreciated. The receiver can remain with my PC and there are no wires to fool with. Lastly, with the touch of a button I can swap to my iPhone and respond to my wife's texts, then immediately return to my desk work. It is this functionality that makes this keyboard worth its weight in chocolate. It's obviously what this keyboard was created to do and it does it extremely well. No issues are present with either my iPad, iPhone or Windows 10 PC. I am quite pleased overall.
