    Logitech makes an excellent product and purchasing this from Best Buy was a no brainer. They have excellent customer service and has always had what I was looking for in stock and at reasonable prices.

    Got this combo on May 2021 and after 7 months the space bar key gets stuck. I do not allow any food or drinks on my desk area, so not sure why in less than a year I have this kind of issues.

    Both the keyboard and mouse were very easy to pair to my computer. Both come with batteries, which also was a great plus. Since install, both the mouse and keyboard have performed flawlessly.

    I liked everything about the keyboard and mouse except that the spacebar key doesn't work most of the time. Very disappointing. With COVID-19 a straight exchange is not possible. Been trying to return on line and there are issues with that as well. Item is not in store so I need to re-order.

    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 liked the look and feel of this keyboard. Unfortunately, bluetooth cut off and on. My computer is less than a year old so it was not the hardware. I tried the usb dongle as well and did not work. I returned this item.

    Stellar mouse. Dumb keyboard.

    While the mouse feels great and tracks beautifully, the keyboard layout is cumbersome, especially on the bottom row. Too many keys are jammed to the left of the spacebar, so I can not accurately hit the Ctrl-C and Ctrl-V combination with my left hand, thus messing up my productivity and making the keyboard pretty useless to me. I'm also not a fan of how the keyboard raises up in the center, forcing me to be poised above the keyboard for proper use. So I'm return this combo and separately getting the mouse (M720 Triathlon) and a different keyboard.

      Hi Keithalicious, we're sorry to see you're unsatisfied with the Keyboard portion of the MK850 Combo. This combo does use the Unifying Receiver signal type, so you can always pick up another compatible keyboard and pair it with the mouse! Hope that helps and thank you for your feedback.

    I figured this one would be a good solution for a replacement to my K350, but I was very wrong. I wanted something that wasn't as loud as the K350 wave, but this keyboard is just awful. Super sticky keys especially the space bar. It does not register strokes and leaves you to correct tons of words unless you really start slamming down with your thumbs. After a week of frustration I tried opening it up and fixing the issue and trashed the keyboard in the process. Back to my loud K350 wave I guess until I find something that works better than this trash.

      Hello, I am sorry to hear about the issues you had with the keyboard. For future reference, sometimes if the keys are not responsive if just needs a firmware update which can be found on the support page for this device on the Logitech site. It also did come with a 1 year warranty so we could have replaced it before you took it apart. Thank you taking the time to write this review, we appreciate the feedback.

    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.

    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.
