Great Keyboard love not having to keep track of a USB plug in and works great

Took a minute to get used to the ergonomic layout, but once that happened my typing speed cranked. The ability to switch over to another device is cool. Love being able to switch to my phone. The live switch over feature works, but can be a bit of a pain.

worked as soon as I plugged it into my computer. looks great and the perfect size for me.

Another solid and reliable keyboard/mouse combo from Logitech. This one has bluetooth as well so you can use it for devices that don't have a USB port for the standard receiver. It has buttons to quickly switch between 3 paired devices, such as a computer, phone and laptop.

The mouse connects using bluetooth or the songle without issue and stays conected. The kayboard has issues staying connected by bluetooth so I'd only recommend if you intend in using the supplied USB dongle.

I made an exchange from MK710 keyboard mouse set to this one MK850 and this one is far better. It allows me to change between devices 1, 2, 3 both with USB and Bluetooth. This is what I've been looking for for years.

This is my go to premium mouse/keyboard combo. I have one of these at all of my offices and also home office. Love the bluetooth connection, i never use the dongle (which is stored neatly under the mouse)

I bought this for everyone in my office. No issues with connecting to any of the computers. Easy to connect via the included USB dongle or Bluetooth.

Good working, its a little slower when changing between computers in comparison to other keyboards with a 3 second delay sometimes

Connecting to PC has incomplete documentation. I finally had to use the 'unifying' dongle. After spending way too much time troubleshooting the issue another website explained that that channel 1 is programmed at the factory to use the dongle. The keyboard has that old fashioned typewriter click so it is noisy & the keys require more pressure than the previous K800. Apparently Logitech is not making soft touch, quiet, illuminated keyboards anymore.

Love the fact that I can use this with up to 3 devices. I currently have it connected wirelessly to my desktop and laptop! Just make sure to use the USB dongle extender. Do not plug the dongle directly to your pc.

Nice keyboard but mouse defective after one year. I bought this kb / mouse combo because the pad is nice for long sessions on my PC for working remotely as well as doing college IT courses. However, the mouse just stopped working, and I have gone through every troubleshooting step and tried the mouse on a different PC, the keyboard still works but the mouse doesn't. I would not recommend spending $70 on something that just dies after a year.

I switch between 3 different computers and it switches pretty fast. Would have been better if the switch on the keyboard switched the mouse at the same time. I does what it supposed to do well.

Thoroughly recommend this as an add-on to a new computer. The keyboard and mouse have such a professional feel compared to the standard devices shipped with my new computer.

The curved keyboard is still a little awkward. Definitely takes some getting used to. Performance is good.

This keyboard features a very well thought ergonomic design. While the travel distance when you press a key is not that great, the typing experience remains fairly good. The mouse is a lighter version of the MX 2 which is a fantastic mouse.

My son finally convinced me to change to a MAC. I like the change, but didn't like the small, light weight, keyboard that came with the MAC. This was the perfect solution. Don't feel like I have to re-learn how to type. Very similar to my old key board.

The way of designing is perfectly. Hand dont get tured when i work.

The keyboard has a good feel to it and I liked the shape of the mouse. However, I work in AutoCAD and Bluebeam. While in these programs, when I would move the mouse, the scroller would move without me touching it and would zoom in and out of the document without my wanting it too. I could probably get use to this function with time but I don't really want to have to mess with that at all. Also, they both lost connection after a few days for no apparent reason and had a rough time reconnecting even though I was using the USB adapter. Oh well. Hopefully they work out these kinks because I love logitech!

I can;t remember of the person who helped me but he was one of the best. I told him what I wanted and he helped me choose the best ones and wrote it up and took care of everything. I was in and out of the store in about 20 minutes. I was impressed!
