Logitech 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.

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.

I handled this keyboard with great care, cleaning it daily and using it very gently. There was no physical damage or impact to either the keyboard or mouse. However, all of a sudden, the spacebar stopped working. I tried everything possible—removing the keycap and cleaning underneath, updating the firmware, and troubleshooting in every way I could—but nothing helped. As expected, Logitech support refused to provide a replacement since the warranty had expired. Following their suggestion, I visited two authorized Logitech service partners in Chennai, fully willing to pay to get the issue fixed. Unfortunately, neither of them was even willing to open the keyboard and inspect the problem. They clearly stated that they do not offer paid repairs and only process warranty replacements, which I could have done online myself if the product were still under warranty. With no support from authorized service centers, I turned to local repair shops. One technician warned me that repairing it would be a waste of time because the build quality is very poor and the internal sheet would likely tear if opened. Despite the warning, I asked him to proceed since I had spent a significant amount of money on this product. As he predicted, the keyboard was completely damaged during disassembly, confirming how fragile and poorly built it is. In short, if this keyboard stops working after the warranty period, it is essentially useless and must be thrown away. I later bought a multi-device keyboard and mouse from Portronics for just ₹1,500, and it has been working perfectly for over two years now. This product is simply a waste of money.

Bought MK850 Multi-Device Wireless Keyboard and Mouse Combo, in Oct 2020 and worked brilliantly but mouse start behaving erratically (left n right button were not responding specially when holding down and dragging ) just 10 days before warranty expires. Service center could not replace the mouse so giving full refund and asked for tons of paper (id, cancelled chq, invoice) , lets see when is money is refunded. Keyboard is very good no issues what so ever. One keyboard k 520 is working for past 6-7 years , another K375 lasted 5 years. I have over 7 dead logitech mouse same problem in all probably not meant for Indian conditions , all die between 13 - 18 months (see pic) -- Finally money refunded and guess what, bought again MK850 but Rs 2000/- cheaper... Review after 16 months (Jan 2023) Again mouse stopped working after 16 months .. Logitech... you disappointed me...

1. Product package and delivery is completely the next level of experience. When I ordered the product the package that got delivered in a box was opened and inside the product box, one of the products (USB Extended Cord) was missing. I have raised these two concerns with amazon and they have initiated the replacement. A few days later I have received the replacement and the same thing has been reported where the box was already opened without any seal and still the USB extended cord was missing in the product box. This is the level of Amazon Data quality checks happening before the product gets shipped and reaches the customer. Also want to mention at the top that this is Bluetooth/wireless connectivity keyboard where if we want to connect 2 laptops/PCs over Bluetooth and 1 with another office/personal PC, then you need to download and install the unifying software or Logitech Options and then only we can use the dongle. Otherwise, it is of no use. Office people who have restrictions on their systems, My suggestion is better to remove this option from your mind. 2. Coming to the keyboard and the mice experience, firstly the key traveling is kind of different, feels soft and responsive while typing. If someone using a mechanical or standard keyboard and opting for this one makes them feel like the keys are placed a bit differently and the tactile response coming from the keystroke doesn't satisfy you a lot. Ergonomic wise it is designed perfectly and the hand rest provided is a soft padded one where the hand sits perfectly without any inconvenience. Need to clean the padding regularly, which keeps it clean otherwise the dust particles settle on top of the padding mesh material. Bluetooth Connectivity of the keyboard is the worst. It takes almost 1min to detect the PC/Laptop and 3/5 times it fails to detect. We need to do some jagged like turn on/off the keyboard and try to reconnect etc. No light indications for the Numlock/Capsloc, although it will show you on the screen when turning on/off. 3. Mice have a very quick response and feel light and satisfying while holding it. The build quality is good and the material is rubber which may leave marks if we don't have proper maintenance. Bluetooth connectivity is very responsive and connects within seconds to PC/Laptop. The scrolling wheel also feels nice, but the one I used is having some issues. Though I scroll it down the response will that I receive is it goes down and again pulls itself up. No issues with Bluetooth connectivity. My review after I used it for 4-5 days: Ok Product, Bluetooth of the keyboard is the worst experience I ever had to date, and secondly, the USB extension cord missing while delivering the product both the times and last but not the least the Amazon Data Quality checks and the package that they are doing these days for the products really SUCKS!. I have returned the product and currently not using it as it didn't meet my expectations.

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

El producto no era nuevo, venia la caja sin el sello original, venia con diurex. No he probado el producto y no se si funcione pero se ve que ya habia sido usado, no tenia los empaques originales de nuevo y tenia pequeños rayones de uso. Ni siquiera apagaron el mouse y tienen un olor extraño entre humedad y cigarro. Lo compre porque anteriormente habia comprado uno y me encantó, sin embargo, me deja mucho que desear la calidad y la tremenda estafa de vender algo usado como si fuera nuevo.

I reality loved the typing experience and the mouse. The mouse is very smooth and keyboard as well. The typing experience is nice. It has a palm rest as well. Overall very good value. I am happy with it.

Have been buying these for my workstations and laptops at home and at work for years. Easy to set up (though Logitech needs to clean up its confusing software - Options+, Hub, Tune, Capture, Unifying), have never had issues, keyboard action is nice and noise level is great (it’s quiet), mouse design, feel.is comfortable and pleasing, and mouse. assignable buttons are useful but not overloaded with feature bloat or magic buttons - clean, focused design. Do wish scroll wheel was quieter, but that’s a nit. Would recommend.
