I have used this device for approximately 3 weeks. I purchased it specifically for the multi-device feature, which is simple to use and works flawlessly. Buttons have a nice feel, and the product generally has a high quality feel to it.
One issue I have is that, on several occasions, when adjusting volume via the volume buttons, it has run away to full volume or no volume on it's own and got stuck there until I reset the device.

I first bought an Apple Magic keyboard then refunded it as it was too small so it made my hand really tired when typing. I search and read a lot of review about Logitech K380/480 and 780 and decided to take this (K780). I am now very happy with my decision. The keyboard is very sturdy, strong body and has a good feeling when typing that doesn't make your hands tired. It also is stick to the table quite well so you don't have to worry about its moving when typing. Anyway, I am very happy that I had swap the Magic keyboard for this one. Yes, I strongly recommend this keyboard to anyone who isn't really with the Apple keyboard.

Oh lordy, so my previous cheap made in China bluetooth keyboard drove me nuts with its 15 second auto sleep, and then it would miss the first character typed when waking. Even web browsing or google searching was a nightmare,

So I got the Logitech K780, not on Amazon, but I'm putting this review here as Amazon is my main source for reviews when I need them:
The Amazon reviews did not bode well, seeming like I was in for another 15-30 second auto sleep nightmare, with no reviews specifying how long the auto sleep could be lengthened to,
In my country, once the box is opened you cannot return the item to the store, you have to do a warrant...view more Oh lordy, so my previous cheap made in China bluetooth keyboard drove me nuts with its 15 second auto sleep, and then it would miss the first character typed when waking.

Anyway I fixed both the missed keys on waking and the short auto sleep for connections to Windows 10 and my Android 9 Samsung S9+,

Go to the logitech website, go to https://support.logi.com/hc/en-us/articles/360024317593
Then click downloads on the left,
Then scroll down to the bottom and click "Show all downloads",
Then chose "Windows 10",
Then scroll down to the entry which says "Logitech Firmware Updating Tool" and under that "this update addresses an issue on certain K375s, K780 and K850 keyboards where the first key press can be lost after waking the keyboard up from sleep."
This is the firmware you want,
This is the direct link https://download01.logi.com/web/ftp/pub/techsupport/keyboards/SecureDFU_1.0.48.exe
Install this firmware using the USB unifying receiver, instructions in the application (can't do this over bluetooth).

I also installed the latest "Logitech Options" software prior to installing the firmware (not sure if this is required), this is found in the same Download list as above called "Logitech Options" with "Software Version: 8.00.863" next to it. The direct link is https://download01.logi.com/web/ftp/pub/techsupport/options/Options_8.0.863.exe

I then went to Windows 10 search and searched for "Device Manager", then went into "Bluetooth", then right click on "Intel(R) Wireless Bluetooth" and go to "Properties", then go to the tab named "Power management", then make sure the box saying "Allow this computer to turn off this device to save power" and make sure this is unchecked.

After this, the firmware results in no missed keystrokes when waking, which I think other people that have updated to this firmware have described.
What other people have not described is that the auto sleep is lengthened to a decent amount. I tested 1minute - no sleep, 2 minutes - no sleep, 5 minutes - no sleep, 10 minutes - no sleep. I gave up timing the auto sleep after this point, I am happy with longer than 10 minutes before it goes to sleep. The infuriating Google searching and web browsing is gone, say for instance if you spend 10 minutes on a website then to find your keyboard has disconnected/gone to sleep. I don't mind paying for batteries every 3-6 months rather 12-24 months, I'm obviously more concerned with the day to day user experience.
The ideal auto sleep for me would be a 30 minute delay. This may have it, however I haven't formally timed it to assess delays longer than 10 minutes yet.

So all was fixed, I then updated to the latest firmware in the same download list "Firmware Update Tool" saying "Software Version: 1.2.169" and "- Brings the latest version of the firmware (FW) to supported devices.
- Bug fixes and security improvements." Direct link is https://download01.logi.com/web/ftp/pub/techsupport/keyboards/FirmwareUpdateTool_1.2.169_x64.exe

Everything has stayed fixed despite updating to that firmware,
Hope this helps,

I type on custom build mechanical keyboards most of the time in my daily work and so I didn't expect much from a chiclet keyboard. It was quite a surprise how nice it felt to type on this thing.I was pleasantly surprised. I love how small it is, how silent the switches are. Probably the biggest con that I can mention is that it's really heavy for a a Bluetooth keyboard. I lift this thing to my lap when I type in an absolutely non-ergonomic (but comfy) position and this thing has some serious heft to it. While this is a problem for me, I understand that this is necessary to hold tablets and other mobile devices. All in all it's a great...view more I type on custom build mechanical keyboards most of the time in my daily work and so I didn't expect much from a chiclet keyboard.

A really good keyboard that makes it easy to switch from one device to another. Only downside is that it's quite heavy. A really good keyboard that makes it easy to switch from one device to another. Only downside is that it's quite heavy.

quickly changes between devices, great holder for your iPad or phone. Personally like the low profile round keys for typing, less miss presses on adjacent letters quickly changes between devices, great holder for your iPad or phone.

I wished it has a caps lock indicator, and can be tilted. I wished it has a caps lock indicator, and can be tilted.

The price for this product is reasonable. The product works fine. It is also portable and easy to carry around. I like the numeric keys as well makes the experience much easier.

WOW. This keyboard is incredible. Was not expecting it to be this good. I usually use a mechanical keyboard but had to buy something quieter because of a new baby in the house. And I'm so glad I did.

Firstly, the feel of the keys is not dissimilar to a mechanical keyboard in terms of feedback. Sure, the amount of travel isn't there but it has a very tactile and noticeable response when a key is pressed. Not mushy or dull at all. The keys also have a very pleasant, slightly textured feel.

The connectivity is fantastic. I use both the 2.4ghz dongle and bluetooth for my laptop and phone respectively. No noticeable connection lag in either ...view more WOW. This keyboard is incredible.

This feature should be ON EVERY SINGLE KEYBOARD. It's life changing. Coupled with the device dock (which itself is an amazing feature) and you've got a futuristic super-setup.

The build quality is top notch. The plastics feel really nice and the hefty weight makes it feel solid. I actually don't mind that it isn't rechargable, the batteries will last up to two years apparently. I'd rather that than have to charge it every week like certain mechanical keyboards lol.

I could go on for ages (can't you tell?) but basically if you need something high quality, quiet, portable with multi-device connectivity pick up one of these bad boys. I got it on sale but I'd happily pay full price for this thing.

Relatively easy to install, directions provided are good!
Use this to go between desktop, laptop and also phone if needed.
Using this on Windows only.
Was easy enough to change receiver from laptop to desktop as well.
Happy with it - and like the low profile keys.
Get the appropriate mouse to make full use of it. Relatively easy to install, directions provided are good!

I use this on a PC, phone and a laptop.

It's great if you need to work on a few things on for work, then switch to write a longer message on your phone and also maybe some light gaming.

Keep in mind that this is a smaller keyboard that doesn't have the typical INSERT, HOME, PG UP / DOWN, DELETE and END number block.

The built in phone and tablet holder is great. The keyboard is quite heavy, and so will anchor well and not tip over with a big tablet.

Bluetooth means that you're not using up a USB slot on a machine. All together, great! I use this on a PC, phone and a laptop.
