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

The price tag might seem to be a bit high - but you can go for it blindly if you are ready to spend for a comfortable and ergonomic combo. Pros: 1. Seamless switching capability between multiple devices. Works very well with my office Lenovo Windows laptop and Samsung Galaxy Tab S7 Android tablet. 2. Keyboard's curved design is very ergonomic. You will appreciate the design once you start using. 3. No need of a USB dongle for connectivity for first two devices you pair. If you need the third device to be connected simultaneously to the first two, only then you will need to use the dongle provided along. 4. Mouse is well contoured for your right hand. Left hand users should stay away - don't buy. 4. Additional buttons on the mouse are completely configurable. There are 3 such buttons (one set similar to the usual forward/backward buttons and the other an almost hard to notice button called Gesture button) 5. Keyboard is 80-90% silent while usage, but has adequate key travel. I felt that the Enter key doesn't have key travel like the other keys - this might improve over time perhaps. 6. The middle click wheel of mouse has a toggle button to switch between ultra smooth and ratchet mode which is a very welcome feature. Cons: 1. Mouse right click and left click aren't quiet. I felt this should've been taken care especially when Logitech already have M221 which is way too cheaper to own in their range which is ultra silent. 2. No Backlit functionality for keyboard - this isn't a big complaint though. I understand the difficulty to manage battery life on a wireless keyboard.

I went for this combo for the following reasons: 1. It is multi-device compatible which means you can use it with Windows/Mac as well as your Android/iOS devices. 2. It has both Bluetooth and a single unifying receiver: You can either use Bluetooth or the dongle receiver that is provided in the box to connect the devices. This is a nice thing to have as you don't have to depend on the dongle and the need to have usb-A ports on the device you want to connect it with. 3. The Logitech Options app is just brilliant. You can use it to check device status like battery and customise various functions of your mouse and keyboard to the next level. 4. I was in need of only a keyboard but the mouse has been quite a big upgrade from my older plug and play mouse. I just can't stop using the hyperscroll wheel and it's other buttons to quickly access various functions like opening control centre or copying and pasting too! This is also an optical mouse that uses infrared as opposed to laser and is more accurate and has a great ergonomic design as well. 5. The palm rest on the keyboard has also come in handy and has a good feel to it. I do face some lag/connection issues once in a while, but it's not something that bothers me very frequently. Overall it's a great buy and I have been completely satisfied with the purchase.

Amazing product especially when you have multiple devices to connect and work with. The bluetooth connectivity of the keyboard is weird at times as the connection breaks and a lot of keys get repeated. Hope this can get fixed with a driver update.

Fantastic keyboard and mouse Combo. Excellent design. The mouse have 6 Extra programmable buttons. And the option of choosing each profile have each individual function is awesome. Keyboard also very good for typing. Keyboard also have programmable Keys. Multiple devices connection was awesome. I am easily switch my Working laptop, Personal laptop and to my mobile. Price little bit High. But it's worth since no other brand not thinking to develop such products. And remember there is a easy scrolling option with one switch. I thought it is DPI switch. But it is Easy scroll lock switch. Which was again awesome option. But only one warranty is bad idea. For this price we can expect 3 years warranty which other brands providing.

Battery never works for 3 years. Worked only for around 2 yrs. Even the device is faulty now after 2 yrs. The mouse click is not working as expected anymore. Would not suggest to buy. Keyboard is good. Noise level is expected.

Best keyboard & mouse combo ever had. Keyboard: The keyboard is ultimate with no noise, feels like laptop keyboard and at the same time felt so comfortable with the elevated design. Can connect between three devices with just a single press button. The shift is instance and bluetooth connection is also reliable. Mouse: The same as keyboard , but it is not silent click. So , yes you will hear a 'click' sound . The swirches between devices is very good. But anyways it has been 1 week since started using this product. Will update the review after 1 year of usage.

works perfectly

Replacement for my old logitech keyboard. I like the way the mouse glides compared to the old one and the keyboard works great

Fiquei impressionado com a qualidade do produto, tanto em questão de software quanto em questão de hardware. Usando o combo de mouse e teclado com o Logi Options+ (programa da Logitech) vc pode personalizar todos os 12 botões do mouse mais 07 botões do teclado. A função de alternar entre os dispositivo conectados (pelo Bluetooth) é super fluida, uso no notebook e no celular. Todos os materiais são de boa qualidade e o mouse é alto e razoavelmente pesado (nada que atrapalhe). O teclado é bem ergonômico, com as teclas em perfil baixo e silenciosas, do tipo membrana. O único "problema" é que só vendem versões internacionais (QWERTY) e não ABNT2, sem o 'ç' e com o acento '~' no canto esquerdo. O teclado numérico tem apenas o ponto, sem tecla de vírgula, mas o Excel fez a substituição automaticamente, reconhecendo o comando como o divisor do decimal. Pessoalmente, todas essas questões com o teclado são apenas questão de costume, sendo até bom exercitar o cérebro e sair do automatismo por um tempo.

this is one of the best product I'd ever buy and I just order another one to use at work It works with my tablet, my regular PC, and I also connect to my work PC for when I bring my working laptop at home; BY JUST PRESSING THE BUTTON 1 or 2 or 3 either on the mouse and the keyboard you can switch from a PC to another AND YOU CAN EVEN USE THE KEYBOARD ON ONE PC AND THE MOUSE ON ANOTHER ONE AT THE SAME TIME !!! :-))))) I was looking for something like that for long time. before I had one set of keyboard and mouse for each of my PC and it was like a nightmare to find place on my desk for the 3 keyboard AND YOU CAN ALSO CONNECT ANOTHER MOUSE OR UNIFYING DISPOSITIVE AND CONTINUE TO USE THIS SET. *** STRONGLY RECOMMEND **** P.S. i've tried almost all kind and brand of mouses and keyboard from Microsoft, Logitech, and some other brand and even for the ergonomy this set is absolutely perfect :-)))

Connects and switches between my desktop, laptop and my Samsung TV flawlessly.
