    Poor bluetooth connectivity

    I purchased this due to the bluetooth capabilities. The keyboard looses bluetooth connectivity, supposedly as a "sleep" mode and takes forever for it to reconnect. Would love to return but it's too late to do so. The mouse stays connected. No real solution from Logitech on the issue as well.

    Been a Logitech buyer/user for decades. This combination of K850keyboard/M720mouse is truly a BIG DISAPPOINTMENT!!!!! The Mouse pointer does not travel through different screens or for example the User wants to write an e-mail, the pointer is not visible in the window where you wrtite the e-mail. Makes it very difficult!!

      That's unfortunate! You can try restarting your computer then re-connect the device. Re-seat to another USB port to see if it works. If the issue is persistent, please reach out to Logi support.

    On the surface this seems like a great keyboard combo, but after trying all of the recommended trouble shooting that came with the product, I was still unable to get the BlueTooth function to connect with my 2017 iMac. If you have a Mac steer clear of this one.

    After using the K780 for years and loving it, I bought the MK850 to try it. I had no problems setting up the K780. I was set up with 2 computers and my cellphone in no time. But now after wasting more than 2 hours trying everything, trying to get support, watching youtube videos, I am returning the device.

      Hello, Thank you for choosing Logitech and for taking the time to review the MK850 mouse and keyboard combo. I am sorry that you have experienced difficulty in getting this combo set up; I would like to help. This combo can connect via Bluetooth/USB Unifying receiver, or a combination of both. This combo comes with 1 Unifying USB receiver. I have attached a link below to the “Getting Started” support page for your combo. Here you will find a setup guide, software downloads and further support. You will want to hold down #1,2 or 3 on the Easy Switch for the keyboard and for the mouse. When the indicator is blinking rapidly, the device is in pairing mode. To pair to a Unifying receiver, you will want to use the Logitech software. Please download Logitech “Options” for customization and a guided setup. I hope you enjoy your MK850. Best regards, John at Logitech https://support.logi.com/hc/en-us/articles/360023300114

    I had no luck with this product. The mouse would go crazy, making my page go up and down when trying to scroll to a particular place on the page. It was uncontrollable even after changing batteries. Unfortunately, I just missed the cutoff for returning it, so I'm stuck out.

      Hi Jhobb21, thank you for sharing your experience with the MK850. I'm sorry that the mouse seemed to go crazy. The mouse (M720) has dual mode scrolling. The button that is just below/behind the scroll wheel controls the scroll if its in precision or hyperfast. Press the button 1 time and see if that helps slow the scroll down for you. Logitech Options Software can be downloaded to give you more control of some of the features for both the mouse and keyboard in this set. I hope you're able to resolve the issue with the tips I've provided. Thank you for being a Logitech customer. Kristi from Logitech

    THIS PRODUCT THREW ME FOR A LOOP. I'M NOT TECH SAVVY, HOWEVER I KNOW THAT A KEYBOARD SHOULD BE READY TO GO ONCE THE COMPUTER IS ON. I DIDNT HAVE THAT EXPERIENCE WITH THIS KEYBOARD. THE 3 LIGHTS ON THE SIDE OF THE MOUSE, EVERYTIME I WOULD LOG IN ONE WOULD BE FLASHING OBVIOUSLY NOT THE RIGHT ONE BECAUSE THE KEYBOARD WOULD NOT LET ME TYPE...THIS IS ANNOYING!!! WILL BE RETURNING.
