Customer Ratings & Reviews

This is one of the best peripherals I have ever worked with and I am in business over 25 years. Easy connection and I love that multiple devices can be used with the device. I would highly recommend the logitech MK850 without reservation.

Bought this combo since my wife has 2 desktops and only one monitor that allows multiple connections to PC. This keyboard and mouse allows you to toggle between the 2 systems using the one monitor. So it's very easy to save desk space with only one keyboard/mouse providing the monitor you have supports multiple inputs. Logitech is a great brand and having been in the IT field for multiple decades you can't go wrong if you require this type of functionality

Love this keyboard and mouse! I can connect it between three devices, my work laptop, personal laptop, and PC with ease through the dongle and bluetooth connections. Super nice and the ability to do a free scroll and forward/backward windows is amazing.

I had been contemplating getting a Blu-tooth keyboard/mouse for awhile. What finally prompted me to get one was purchasing a new laptop that I intend to use to replace my current 12 years old desktop build. I did not want to use the laptop keyboard/mouse nor a USB connection for the dongle of an external keyboard/mouse - solution - blue-tooth! I like this keyboard a lot and do recommend but it has its quirks. Also having the option to use the USB and the provided dongle gives piece of mind if every using a device that does not have blue-tooth. Make sure your device has blue-tooth - for Windows 10 click settings then blue-tooth and other devices. If you have blue-tooth you should see blue-tooth option and be able to turn it on/off. The keyboard and mouse are paired separately. I had better luck doing keyboard 1st then mouse. There are 3 pairing "band" options so make sure keyboard and mouse are using the same. Then press pairing button on either keyboard/mouse and in Windows 10 select add a device then mouse/keyboard... device should scan and devices and select keyboard k850 and it should pair. Duplicate for mouse and select m720 triathlon. Once paired you are set to go but I would recommend downloading the Logitech software from website. It allows you to set up more details/options. I have not had any issues with dropping the signal/device. No issues waking up laptop from sleep but it does take a second or 2 before mouse fully functions. Nice feel from keys and I like size/shape of mouse. Mouse has option to turn off "click" when scrolling. I used it for awhile but reverted back to "click". Also mouse has a button at bottom of right side that if clicked brings up screen that shows all open windows kind of nice option. Keyboard is supposed to work with Windows or Apple but I don't have any Apple devices to test that. Some keys are multi-function requiring you to hit function key before using. Pretty common for laptop keyboards but a tad dis-appointing for a full size external. Also no back-lighting on keyboard. Overall its worked great for me and do recommend. Whats not to like having option to use with Windows or Apple device as well as ability to use blue-tooth or USB dongle - whats not to like?

Great keyboard. Functions well. Keyboard and mouse can pair with three devices. Easy to setup and use. Great battery life.

I needed a second keyboard and mouse combo. This combo is a decent performer. I like the size of the keyboard and mouse. They are responsive and battery life is great. No major issues so far. The only issue I don’t like is the placement of the desktop switched button. It’s placed in the most convenient spot for my thumb just below the back and forward buttons. I don’t use that feature so I sometimes I accidentally hit the button and change the desktop setting. I also felt the keys were mushy at first but overtime they became more clicky so it’s fine now.

This is the best keyboard I have found. I like the feel, size (not as bulky as some of the other Logitech keyboards). I especially like the fact that you don't need a receive to connect the keyboard and that you can pair the keyboard and mouse with up to three devices. Just press on a button and you are connected to your other devices. Super easy and convenient. No more removing the receiver from one device and plugging it into the other devices.

Ergonomic keyboard and mouse work well. Serves our needs.

As plug and play as you can get. Very convienent for my ergonomic user requirements.

Perfectly acceptable for office work and web browsing. No, it’s not my kid’s Razer super crazy mouse and keyboard but it’s a great option for my wife who works from home and doesn’t want the clutter of wires. She’s about a month in and the batteries are holding up fine. I’m not saying the batteries are bad…just a personal choice. If they die she can begin working again immediately vs waiting for them to charge.

I have multiple computers, so the seamless transition by a click of a button from using the keyboard and mouse for one computer to another one is outstanding.

Surprisingly high quality and great user friendly features. Easily being able to switch between pre-linked devices was something I didn't know I needed until I got this combo set. Powered by AA batteries, I have had this set for over a year, used almost every day, and have not had to replace them yet.

Works great! Connects to multiple devices to makes a seamless transition from one to the next with the click of a button. Cushion for wrists to rest on too!

At first was wary of the curved design but I was delightfully proved wrong! Very comfortable typing position and wrist rest. The fact that I can switch between typing and using my mouse on my work laptop and navigating and typing on my iPad with a single button click is amazing. 10/10!

Great product! Perfect size and contour for regular desk work. No complaints!

Love this keyboard and mouse! First time I got it from my job and after the change of job I bought it. Very convenient, ergonomic and great for whole day of typing and work.

It works very well. Comfortable and responsive keyboard. Would purchase another one if I needed it.

Works very well, I am happy with it. Two things for me gave it a 4 star instead of 5. The mouse was very sensitive and the page would keep scrolling. I did find a way to change some settings to stop this, but did not see anything in the documentation pointing to these settings. The other is personal preference. I think the keys on the keyboard are a little light. I like a more solid feel, I keep getting extra letters if I hit a key and brush against the key next to it. I am adjusting my typing, so overall this is a good setup.

Keyboard/Mouse combo are easy to set up, and comfortable to use. This is the second set I have purchased, this one being for my college student. Never had an issue, connects to multiple devices easily and seamlessly. Highly recommend.
