LogitechK780 Multi-Device Wireless Keyboard for Computer, Phone and Tablet – FLOW Cross-Computer Control Compatible - Speckles, White

Great product has lasted me 6 years. Bought and super happy

This keyboard is great. I got this for someone else in my home after they tried my K380 (Which is basically the same keyboard minus the aluminum holder at the top and no numpad on the right). They're super happy with it and loves how the keys feel and operate. This isn't a mechanical keyboard but still super nice. One of the best things about the keyboard is the ability to pair it with 3 different devices. To change between devices you just have to push the corresponding button that matches the device you want to use. The keyboard is Bluetooth and also comes with 2.4Ghz Logitech unifying usb receiver. It's powered by two AAA Batteries. To remove the battery cover you slide the door towards the center of the keyboard and not to the edge like you would imagine. The keyboard does have a power switch on the right narrow edge that you can manually power down with but typically you won't need it as they keyboard does go to sleep after not being used. If the keyboard goes to sleep you will want to press the button that corresponds to the numbered item you want to use, you will need to wait a moment until the button stops blinking. To pair the device to something using bluetooth simply press and hold the numbered button until it blinks rapidly then open your bluetooth settings and locate the keyboard in the list of devices. This keyboard is labeled for both a Windows computer and a Mac. I personally use the keyboard with a Mac.Pros:Great keyboardVery well madeComes with Duracell batteriesComes with a unifying receiver for devices that may not have bluetooth or if you don't want to use it that wayKeys feel good when typing and are a good size for small or large handsCan be used with a total of 4 devicesEasily switchable between multiple devices with the push of a buttonSwitch to manually power off, this would be good if you need to take it with you and need to toss it into a bagCons:If you must have a device with its own built in rechargeable battery this one may not be the keyboard for you.No way to remove the aluminum stand if you don't plan to use itHas a bit of extra weight from other keyboards but that's likely due to the aluminum

I got my first one in 2017 and this is the 5th I've ordered (not sure where one of them is). My current one just lost a key cover but is otherwise fully functional--but I cannot find the cap!I tried the "updated" one by Logitech that can talk to multiple devices because I think Logitech stopped making this one...I returned it the next day. Everything I love about the K780 was missing. I use the one dongle for the keyboard and matching M720 mouse. I only use blue tooth for my phone, when I need to type extensively in messaging or Whatsapp. Just faster and far more accurate than voice recognition...and the phone sits nicely in the slot at the top so I can see it--works great for a tablet as well.I don't mind the battery changes. I've had their solar-powered keyboards die even with replacement rechargeable batteries, and never come back to life.The only keyboard I ever liked as much was the ORIGINAL IBM PC keyboard from 1981--useless today, of course.

I recently started working from home. This has brought about a few hurdles, one being I have my personal PC, which is also used for doing some work for my job. I also have a personal laptop PC, with it's own mouse, which I use for photo viewing out in the field. Then I have two dedicated PCs for my job. I have two monitors on my desk and was using two keyboards and two mice. When I had both PC's fired up it became a bit confusing and I was constantly trying to use the wrong mouse and/or keyboard for the wrong computer! Even when I would move one keyboard out of the way, intending to use one PC, I found, at times I needed to use both simultaneously. So I began looking for options...enter the Logitech K780.When I first took it out of the box and checked it out I was going to return it, due to the fact it has no Caps Lock or Num Lock lights on the keys. I boxed it back up and set it on the counter to return. Then I decided to see if I could find some videos on the use of this keyboard. I did and I decided to give it another try after watching a couple of good reviews on the use of it. I also ended up buying the Logitech M720 Mouse in conjunction with the keyboard. I have been using this set up since April 25th, 2021. Here is what I have found:Positives:1. It really cleaned up my keyboard/Mouse nightmare and saves me space!2. Downloading the software for these devices makes them extremely useful. The ability to copy a file from one computer to the next is awesome!3. Moving the mouse from one desktop to the other allows the keyboard to switch automatically, which is pretty convenient.3. I am a horrible typist and this keyboard certainly helps me out with the exception of a few things, due to the fact this is a compact keyboard. The keys are nearly silent and the way they press down is fairly effortless yet positive. They bounce right back after pressing them down...something my last keyboard for my work PC was horrible at!4. Battery life seems to be excellent. After one month of a lot of use, typically seven days a week and probably 8-10 hours per day the keyboard battery is still indicating a full charge.Negatives:1. There is no Delete, Home, End, Insert or Pause/Break, Pg up or Pg dn keys above the arrow keys. The delete Key is at the end of the row of F Keys above the large Back Key. I use back and Delete a lot!2. Num Lock and Caps Lock have on-screen indicators, but no lit keys. Somebody that types well may not be bothered by this, but I need to focus on my keyboard, very intently or my sentences come out like somebody that is extremely drunk.3. When moving between desktop I have to allow the keyboard to switch and there is around a 2 second delay. The F1, F2 and F3 keys indicate what device the keyboard has connected to, so you have to pay attention.4. When using the Volume Down key, it will go to Mute and then will not allow me to turn the volume back up until I switch from the desktop to the other desktop and back and/or close out my browser and re-open. I find this annoying at times, but it may be something I am not paying attention to.Over all, I would definitely recommend this keyboard with the mouse to aid in the use of 2-3 devices. I have opted to not connect to my 3rd PC as it is not integral to what I do with the other two. I do have a third monitor which I use as to view Construction Plans on a 43" 4K TV. I have not connected any of my devices via Bluetooth and prefer to use the Logitech Unifying Receivers. If I have both PCs on and the big screen I have to scroll all the way across the work PC, then the big screen to get back to my personal PC. So I leave the big screen turned off as much as possible. I may be able to connect to it via Bluetooth and or a Unifying receiver, but have not tried that to date.All in all I am pretty pleased with not having to use different keyboards and mice to operate my two main work machines!
