I bought this keyboard because I wanted a wireless keyboard with a numpad and device switching capabilities to support my Windows PC and two iPhones. However, this keyboard falls short in every way so I returned it.
First, the keyboard itself is quite heavy because of the built in mobile device stand. I think the stand was a cool idea, but in practice is not very useful for me because I like typing with the keyboard in my lap and so the device’s screen ends up uncomfortably close and low relative to my eye level.
Second, the wireless connectivity was quite spotty beyond 3 feet. When switching devices, if I was too far away from the USB receiver I’d have to get closer momentarily before switching, after which I could go a few feet further back, which was annoying. Also, my first few keystrokes after having the keyboard idle for a while or switching devices consistently were not detected, so I had to keep backspacing to retype my first word. I used Bluetooth to connect to my mobile devices, which seemed to work OK, but I put the devices on the stand, so I don’t know how well it works from a distance. Regardless, even with Bluetooth some of my keystrokes were still not detected.
Third, the keyboard layout itself is kind of weird. I didn’t realize when I bought this keyboard that it is not actually a full-sized keyboard despite the numpad and I found myself missing the arrows and insert/home/pageupdown/etc keys being in their regular place on a full-sized keyboard instead of being compressed alongside the alphanumeric keys and having to use Fn keys to toggle certain behaviors. Also, by default, the F keys at the top require you to use the Fn key, so things like Alt+F4 become Alt+Fn+F4 to close windows. The only way to force the F keys to behave as F keys without using Fn is to download some special software called Logitech Options, which again was pretty annoying.
Perhaps the more egregious error that I found with this keyboard was that the Windows Start key and the Alt key were swapped (as in the keys were labeled correctly and had correct placement, but pressing Alt would bring up the Start menu and I had to use Start in place of Alt for some keyboard combos, like Start+F4 instead of Alt+F4) for some reason that I was not able to resolve, even with the Logitech Options software. Additionally, the right Ctrl and right Alt keys simply did not work at all. Logitech tech support is also pretty lousy and didn’t get back to me for weeks when I had already returned this keyboard out of frustration.
In conclusion, if you’re looking for a full-sized wireless keyboard with device switching capabilities, don’t get the K780. Instead, I recommend the K375S, also by Logitech. The K375S is full-sized, wireless, and has essentially the same device switching feature as the K780. The wireless range through the unifying receiver USB dongle is also not great, but I have no complaints after switching to Bluetooth. I have encountered significantly fewer issues with my keystrokes not being detected using this keyboard and all the keys function as intended. I still needed to install Logitech Options to force the F keys to behave like F keys without using the Fn key, but that is a minor annoyance relative to everything else. Also, the K375S comes with a detached device stand that you can place further away from the keyboard, like on a table, which makes the keyboard itself much lighter than the K780 since it doesn’t have all that extra weight of the stand.

I’d actually say that it’s a 3.5 / 5. Shortcomings: – slightly short on it’s width, unnecessarily cramping the type strokes – no Caps Lock LED – a real nuisance, espcially with passwords – no recharging / USB power connection… …so it comes down to polluting the world some more with AAA batteries Strengths: – it works in terms of being able to span up to 3 machines, various OS, on the same network. – sometimes a wee bit slow to figure out where you’re actually trying to type, and I’d say about 95% synced with the mouse – definitely should be used in conjunciton with the Logitech MS Anywhere 25 (or whatever the name sequence is) latest versions So, a brilliant product, hampered by some annoying basic design flaws, which is really unfortunate because I think otherwise Logitech’s really got the future of these devices figued out in the near term for sure.

This thing is perfect. All I wanted was low keys (super short throw). I got it with this and keys are quiet and fun. Round also keeps me from catching corners of other keys when typing fast. Delete button is a must (Wth Apple?).
I’ve been waiting for there to be a keyboard that can instantly switch between devices. Bonus that it holds the devices too. I use the USB receiver with my Win10 laptop (on a desk stand next to a second monitor). I put my Iphone and Ipad in the keyboard rack. With the touch of a button I switch instantly between the three devices. Fast texting and writing to calendar on I devices while working on laptop etc.
Keyboard is heavier than most, which people equate to quality. For me maybe it makes it more stable.
Batteries are included, two AAAs.
Usb receiver storage next to batteries.
Connect your other Logitech devices to this usb receiver with the Unifying program at Logitech site. Amazon won’t let me give you the link. I combined an old mouse and it all works on one usb receiver.

Bought this keyboard and has been using it for a month. I am sad to say that this keyboard has a auto sleep feature which cannot be turned off. It is so irritating when the keyboard will go to sleep mode after 30seconds without activity. You will miss the the first character you trying to type when it goes into sleep mode. Whoever who design this feature should be fired !!

There is so much to like about this keyboard: it’s satisfyingly heavy, the keys are firm and snappy, and the promise of one keyboard to rule all your devices is very enticing. Alas, it suffers from two fatal flaws that make it completely infuriating to use.
The number one problem is that it forgets your settings. This keyboard has function keys along the top that also double as hotkeys for things like volume control, context menus, and so on. By default, they are hotkeys; in order to use them as regular function keys, you have to hold down the Fn key. That is to say, by default, just plain F5 is not an F5 but rather a “context menu” command. Similarly, F10 is not an F10 but rather a “mute audio” command.
I’m a programmer, and I use the function keys all day long. I need to be able to press them with one hand and use the mouse in my other. Not to worry! Just install the “Logitech Options” software and you can swap the defaults so that the function keys behave normally. Problem solved…or so you thought.
The keyboard regularly, and randomly, just forgets your settings. You’re debugging some code and using F10 to step over, step over, then suddenly MUTE for no reason whatsoever. Sometimes this issue fixes itself within a second or two. Sometimes the keyboard just decides that’s the new way things are going to be. I could not discover any rhyme or reason to this. It invariably happened, well, when I was trying to use the function keys to get something done.
The other problem is that at similarly random intervals, the keyboard stops sending keystrokes for a few seconds. Sometimes it’s just a few seconds. Sometimes it’s 20-30 seconds or more. Not a huge deal, except when you’re in the middle of getting something done and you have no idea when your keyboard will start functioning normally again.
I wrote to Logitech about this and received a canned-text reply that sent me to user forums and encouraged me to change my batteries (they were fresh). Incidentally, the function key problem is well-described on the Logitech forums.
I gave the keyboard two stars because when it works, it works great. Sadly, “mostly functional” is just not enough for a keyboard. I have a Logitech mouse that I love. I wanted this to be great. It has easily been the most frustrating purchase of the year.
For what it’s worth, I’ve switched to the HP Wireless Elite v2, and, while I’ve only had it a day, it works perfectly so far.
Best wishes and happy typing!

I ordered this keyboard after considering and trying out several models within the Logitech line. I bought it for its heft and form factor (it is a very nice-looking keyboard), extremely quiet keys (I’ll be using it in a recording studio), and ability (or so I thought) to connect to multiple devices easily via Bluetooth. My work area contains an iMac, a Macbook Pro, and iOS devices. Photo shows other devices to give some idea of the proportions of the K780.
One of my tests was to run my fingertips over the keys. With most keyboards, you get that slight clicking noise from the play in the keys. Not so with the K780. The keys are firm in their positions. I found that for my typing style this makes for very confident and precise touch typing.
Problem: I have had a hard time connecting at all to Mac OS Sierra (10.12.3) via Bluetooth, The K780 doesn’t even show up as an option in the Bluetooth setup screen, but the Unifying wireless works perfectly even on a 10 y.o. iMac running Snow Leopard (10.6.8). However, I have not been able to keep that Unifying connection to my iMac working when I enabled Bluetooth to connect to an iPad. Upon further post-purchase research, I discovered that there are known Bluetooth issues with Sierra. None of these cropped up in the reviews I read here; in fact, the opposite. Other than that, I want to love this keyboard and am still giving it 4 solid stars because it looks and feels great and absolutely works as advertised in Unifying mode. I hope to bump my review to 5 full stars if I can find a fix for this issue with Sierra. In fairness to Logitech, I believe that this is a Mac issue, not a problem per se with the keyboard.

I purchased this in October 2018 and in Late November 2018, I noticed the backspace key would not work each press and upon further review, I noticed that the back space key was depressed to the left side and I would have to constantly move my hand and hit the right side to “unstick” it. I contacted logitech support and they asked that i blow out the keyboard with compressed air and I did same without much improvement. They have sent me a replacement product free of charge and I will revise this review should the model I got be a dud. For reference I have used a Logitech solar K750 prior to this for over 5 years and all keys work fine. I just replaced it due to the smaller form factor and ability to type on my cellphone or tablet via bluetooth quickly. Which that works great. the TLDR I gave it two stars for the service I received from Logitech.

I’m giving this thing five stars but let’s be honest, it looks like it was made by Fisher Price. It’s a bunch of round plastic buttons on a plastic base with a white plastic phone-holding lip on the back. I saved the $10 and got the white one because the speckled one sounded even uglier, and that’s saying something.
Setup was stupidly difficult, too. You have two choices: Bluetooth or the USB Unifying Receiver. One USB Unifying Receiver is included with the keyboard but since the whole point of the thing is that it supports three devices, you might need to buy one or two more for your use case at about $13 each. Once you’ve got those, you’ll need to install the Unifying Software on all devices using USB Unifying Receivers and it will prompt you to turn off the keyboard and turn it back on as part of the pairing process. It’ll even tell you where to find the on/off switch. Except one problem: there’s no on/off switch on this thing, so you’ll actually have to pull out a battery at that point in the setup and quickly put it back in. That worked for me at least, but it’s stupidly clunky. At least Bluetooth setup is easy and fast.
There are no home or end keys, so you’ll have to turn numlock off and use the keypad if you want those features. No print-screen either, although Windows Snipping Tool has made me forget about that key even when I have it. They did manage to squeeze in four arrow keys which is nice. Overall typing feel is very good for me, but I adapt easily to new keyboards generally. I’m touch typing this review on the K780 and have made no more mistakes than usual for me.
This thing logically matches up with the Logitech M720 three-device mouse, but if you get both (as I did), you’ll find they don’t switch devices together. You need to change the keyboard to the device you want and then change the mouse separately, which seems like something they could automate easily but haven’t.
Why five stars given all my complaints? Because nobody else makes a multi-device keyboard that I can find, and this thing makes KVM switches obsolete when paired with the Logitech M720 three-device mouse and a multi-input monitor, and that setup has none of the cable clutter that comes with KVM switches. For me, that outweighs a stupid setup process, and it might even outweigh the general ugliness of the keyboard. I’m not sure about the latter point, which I realize makes me sound superficial but I pride myself in my equipment and have pretty high quality gear and this children’s-toy-looking keyboard just doesn’t fit in with the kind of atmosphere I’m trying to create in my workspace. For now, I’m keeping it for the multi-device functionality, but I’ll keep my eyes open for upgrades. If Logitech made a better looking, better feeling version of this for say $50 more, I’d buy it in a minute.
Decide how important multi-device functionality is to you because this thing is ugly. Factor the M720 three-device mouse into your plans as well if you decide to go ahead.

UPDATE 2021-03-02: I gave the K780 another try together with the M720 mouse. They are an excellent combination. I can assign what I need to the extra mouse buttons. No problems with Blender. I’m very happy with this keyboard-mouse combination. Five stars again. 🙂
UPDATE 2020-12-26: I’m going back to my K4. Unfortunately, the K780 num lock toggle doesn’t work for Blender on Windows. I’m forced to use my left hand on the fn key to access the navigation keys. Same goes for MacOS. It’s a mind-bogglingly silly oversight on Logitech’s part. It would’ve been a nice keyboard, but with this problem, it’s not worth anywhere near $100 CDN.
ORIGINAL REVIEW FIrst, a little background. I have been using the K380 for a few years. It has been my favourite keyboard until now. When I started coding professionally, I got a Keychron K4 for the numpad and the clickety-clack of mechanical keys, but there were wonderful features of the k380 that were missing on the K4. For example, there is a keystroke buffer on the K380 that remembers your keystrokes while the keyboard reconnects from sleep. That means keystrokes don’t get lost if you take a break from typing. The K4 didn’t have that. So I had to have it plugged in all the time. Also, the K380 seamlessly transitions between my devices (Windows, Mac and Android… and sometimes Raspberry Pi). It is100% reliable that way. Finally, the battery life on the K380 is unmatched.
Enter the K780. The K780 is all of these things minus portability. I initially got it because the numpad is useful for Blender (lots of keyboard shortcuts). It’s also highly durable. I’m very happy with it. I’ll use it all day, every day. This is the only keyboard I’ll ever need.
If there’s one criticism I have for the K780, it’s the lack of a numlock indicator. I can deal with no capslock light because capslock itself is an outmoded feature (seriously, typing all-caps should be banned by 2021), but numlock is essential for alternating with home/end/pgup/pgdn. If I’m in the wrong mode, the results mess up my workflow. If the decision to omit an indicator was made to conserve battery life, they could have put in a mechanical switch, like a latching button, to toggle numlock instead.
I haven’t tried the FLOW feature, but one of these days, I’ll get around to it. Either that, or I’ll upgrade to a multidevice mouse.
If you like your K380, but you wish it had a numpad and don’t mind sacrificing portability, get yourself a K780.

The K4 didn’t have that. So I had to have it plugged in all the time. Also, the K380 seamlessly transitions between my devices (Windows, Mac and Android… and sometimes Raspberry Pi). It is100% reliable that way. Finally, the battery life on the K380 is unmatched.
Enter the K780. The K780 is all of these things minus portability. I initially got it because the numpad is useful for Blender (lots of keyboard shortcuts). It’s also highly durable. I’m very happy with it. I’ll use it all day, every day. This is the only keyboard I’ll ever need.
If there’s one criticism I have for the K780, it’s the lack of a numlock indicator. I can deal with no capslock light because capslock itself is an outmoded feature (seriously, typing all-caps should be banned by 2021), but numlock is essential for alternating with home/end/pgup/pgdn. If I’m in the wrong mode, the results mess up my workflow. If the decision to omit an indicator was made to conserve battery life, they could have put in a mechanical switch, like a latching button, to toggle numlock instead.
I haven’t tried the FLOW feature, but one of these days, I’ll get around to it. Either that, or I’ll upgrade to a multidevice mouse.
If you like your K380, but you wish it had a numpad and don’t mind sacrificing portability, get yourself a K780.
