    If I didn't throw away the box, I'd return it.

    The keyboard was TERRIBLE. I would not detect the letter "a" and I would have to hit that key several times. It was overall very slow and lagged considerably. I moved the receiver right next to the keyboard and mouse, and it didn't help. I also limited other wireless devices, and that didn't matter either. The mouse is okay, but sometimes the volume control sticks and I have to turn the mouse off and then back on for the volume controls on my speakers to return to normal. I would not recommend this set.

    Loved the mouse. Sensitivity of scroll wheel might be too much for some. Keyboard was meh. Used for a few days and then it stopped working on any computer with fresh battery change.

    I wouldn’t consider this anything fancy. The buttons feel cheap, the mouse feels cheap and response time is pretty much terrible. Looking for a low cost combo? This will get the job done- but don’t expect gaming-esque controls or quick typing. Keys almost fee sticky.

    This keyboard is too soft for my liking. I have to really press the keys in order for the information to pop up on the screen. The mouse was great. The keyboard, not so much.

      We're sorry to hear that the keyboard in the MK850 combo doesn't meet your preference for keypress feel and requires more force than you like. It's good to know that you found the mouse to your liking, though. We appreciate your feedback on the keyboard's responsiveness. Logitech

    In the space of just two months, I lost count of how manys times the Bluetooth connection stopped working, each time requiring a combination of tricks to solve the problem. The last round, however, I tried every recommended permutation to attempt recovery and nothing worked. Two months of unreliable use and now I have to buy something else because this device is unusable. Such a disappointment from Logitech and I hope this review saves others from regular frustration.

      Hello, I am sorry to hear about the issues you are having with this keyboard. This keyboard does both Bluetooth and USB connection for a wireless experience. The USB dongle is always going to be the more reliable connection. I hope this helps. Thank you for taking the time to write this review.

    I ended up returning this. Description does not mention “ergonomic” features, but the curves are in the keyboard. Extremely uncomfortable for me. I got the 650 instead.

    The keyboard is a bit soft. Wish the function keys are in normal size. Since this is a curved keyboard, my fingers are not long enough to get to the F5 key which I used a lot in wring MS SQL. Mouse is OK.

      Hey there SLY3, I'm sorry to hear you had some issues with your MK850. Using our Logitech options software, you should be able to set different macro keys to the buttons on your mouse as well as your keyboard, which should solve your issue with the F5 key. -Weston from Logitech

    We reset the unit twice, switched the controls and read the manual, the unit does not work, does not make ice and is not cold. Only thing that works is the water dispenser. Delivery team was awesome.

    I worked with Logitech and it was a complete disappoinment. I sent them logs and they had me try multiple configurations and nothing worked. It would lag, skip and not follow from computer to computer.

    expected a lot more from this keyboard but Logitech has let me down on this one. the keys seem to get stuck if you are typing too "fast" and it just doesn't have the ideal feel for someone that uses it for 6+ hours a day.

    Being disabled I needed a keyboard and mouse that had the ability to function more than just me PC. This system works well with any blue-tooth enabled item and has quick connect buttons to change from your items as you work. Bravo Logitech...……….

      Hey there, I'm sorry to hear about your connectivity issues with your keyboard. I would recommend making sure the batteries are properly seated and fully charged inside your keyboard, and possibly try using a different USB port on your computer if you can. If you're still having issues with the keyboard after that, feel free to contact our support site for warranty information.

    Wish this keyboard and mouse came with three separate doggles to use. Instead of one dongle and two Bluetooth for this enabled keyboard. I have never had great luck with the Bluetooth with this device.
