MK850 Multi-Device Wireless Keyboard And Mouse Combo, 2.4GHz Wireless And Bluetooth, Curved Keyframe & Wireless Mouse, 12 Programmable Keys, 3-Year Battery Life, PC/Mac, QWERTY UK Layout

I have always been a avid fan of Logitech from having their PC speaker back in the day to having their keyboards. So it made sense to buy this MK850 Multi device wireless keyboard & mouse Combo when I needed a input device for my custom built PC, tablet & Xiaomi 14 Ultra. The beauty of this MK850 Combo is that at a press of a button I can switch between all three of my devices seamlessly. Previously I would have needed separate dongles or cables, but with the MK850 there is 1 dongle for the PC and my tablet & Android phone connect via Bluetooth both to the mouse & full size keyboard. The K850 keyboard is very nice to use with a comfortable palm rest, soft tactful keys & has a long battery life. The M720 Triathlon mouse has a contoured feel that fits snugly into your hand. The buttons are well placed & once again have a pleasant feel to them when pressed. I use the keyboard combo for home office work primarily however, the combo does perform adequately when I use it for online gaming.

I bought this to replace the Logitech Cordless Desktop MX 5500, as I do a lot of home working. Switching between my work laptop, home laptop and home desktop on my small desk was a pain. No longer, with the MK850 switching is a breeze. This keyboard and mouse can pair via Bluetooth or Unifying receiver to up to 3 devices. Then swapping between paired devices is as simple as pressing one the white keys numbered 1-3, and clicking a button on the side of the mouse to cycle between 1, 2 and 3. The combo comes with a single Unifying receiver. I put this receiver into my home desktop, I paired to my laptop using Bluetooth and my work laptop using a Unifying receiver I have with my older Performance MX mouse (approx 2014). The pairing process was smooth and seamless for the more modern machines. I did try to use Bluetooth for the work laptop but the one I had at the time was older with Window 7 and did not support the enhanced bluetooth needed for these devices. I have a new work laptop now so could try bluetooth with that but it works great with the receiver still in it so I'm going to leave it alone. For the windows 7 machine which had the Setpoint software on it, I had to go into the Unifying software to pair the mouse and keyboard. I had trouble with this the first attempt but it worked fine the next time I tried. However there is a workaround using the unifying receiver if you have trouble pairing with a particular machine, which is to plug the receiver into a different machine, and pair to that using the Options software, then just plug it back in the original machine! The work laptop with its unifying receiver is also still paired with this older mouse that I keep in the laptop case. So when I'm at work I switch on that mouse and it works perfectly as it did. When I'm at home I leave that mouse in the bag and click the device button on the new mouse. It all works very smoothly. If you use the new Logitech Options software (replacement for the older Setpoint software) on all your devices you can configure something called Flow which will seamlessly switch mouse and keyboard between your devices as you move your mouse cursor off one screen onto the other! I haven't tried that yet as I don't have admin rights to my work laptop so I can't install Options on that. Note that you don't need Options to use these peripherals. The keyboard in this set is the K850. I don't know if this can be purchased separately. It has a better more positive action than the MX 5500. With that, many keys would stick a little if you strike them at the corner. This does not happen with the K850 When new it feels quite "rubbery", a very damped travel, and is very quiet. In use however this loosens up considerably and gives the feel similar to many other keyboards of reasonable quality, together with the usual slightly clacky noise you get from most keyboards that get heavy use. It's not a particularly noisy keyboard by any means, but it is a big contrast between new and virtually silent and worn in. It has a traditional key layout with all the function, control and cursor keys in the "right place" for a UK keyboard. The "windows key" is labelled the start key as it has a different function on a mac. The keys with different function or mapping on a mac are labelled such, with a line separating their displayed mac function from the windows function. The keyboard has two tilt angles from the folding support legs, 3 if you count "flat" with the legs folded away, which I use. The main keyboard area has a slight curve for ergonomic reasons but to me it just feels like a comfortable "normal keyboard" in use rather than a special ergo one that would need getting used to. The fixed palm shelf is some sort of soft touch textured rubber with a woven fabric texture. It feels nice but I'm sure it will trap dust and debris and will not be easy to clean. The mouse is labelled the M720 and can be purchased separately as the "Triathlon M720". This is a much less sculpted affair than past mice like the MX Revolution, and a bit smaller. It is clearly designed for right handed users but while not ambi, I think left handers could use it without it feeling too awkard. The issue for left handers would be the button placement. It has two programmable thumb buttons which default to browser forward and back. The button behind these is the device switcher. The free spinning ("Hyperfast scrolling") scroll wheel functions like most mouse wheels as a "third button" if you click down on it, and supports side scrolling if you tip the wheel left or right. Behind this is the mechanical switch button to toggle between free spinning and click to click function on the scroll wheel. Gone is the software controlled function of the MX Revolution but you gain the standard third button function in return. I can't comment much on battery life as I've only owned it for 4 weeks now but the manufacturer claims 24 and 36 month life from the mouse and keyboard respectively, from the non-rechargable batteries supplied. 2 x AAA for keyboard and 1 x AA in the mouse. The Options software still reports battery full for both. Certainly far better than the 2-3 weeks of heavy use from the rechargeable Performance MX and the 4-5 weeks from the MX Revolution. In summary I'm extremely happy with this purchase. I wouldn't have bought either separately without the multi-device capability but even without that capability, the keyboard is the best I've owned and the mouse is about as good as the Performance MX.

I like: The seamless ability to switch from work laptop to my PC without moving the unifier around each time. I like the mouse, which is well made and has two scrolling modes. I don't like: The keyboard is a little small, and the "wrist rest" does not feel adequate (thick) enough to support your wrists. The keyboard feels cheap to me. Okay for work but not great for gaming. I personally would like quieter keystrokes too. Still, I am coming from a Microsoft Comfort Keyboard which was amazing to use and had a great wrist support, but the mouse started to die and the keyboard was probably going to be next (both were 15 years old!) so it was time to change things. So my conclusion....if you frequently PC game, as well as work from home - i would probably go with the new microsoft comfort curve option. However, if you don't game and have a laptop/pc and work from home and want the minimum fuss and ease of use, then this would be perfect. 4/5, loses 1 star because of the small, not very comfortable keyboard.

Niestety zamówienie z 5.09.2025 jeszcze do mnie nie dotarło.

Extremely easy to use. Setup is quick and easy. Bought it because i use it with both windows and MacBook

awesome product and it was like new!

Pour le moment rien à dire. Installation facile.

Dopo un paio di mesi di utilizzo devo dire che è veramente una buona tastiera e mouse, unico difetto del mouse riguarda la rotella che quando lasciata in rotazione libera a volte si muove da sola per via del proprio peso non bilanciato. Con un po' di manualità è facile correggere questo difetto.
