    It tends to be over-responsive causing the page to flip without moving the mouse. I’ve never experienced this before with either wired or wireless mouses.

    Like the new keyboard & easy to set up. Only thing I find difficult is the largeness of the unit - too many typos since I’m used to a smaller keyboard.

    I have 2 for my business. They both perpetually lose contact and will quit working. Like everyday. It is not the batteries. The dongle is withing 3 feet of both keyboards. It is annoying and I am resentful that I paid this much for these that are untrustworthy in a business that needs them to do business

      Hi Dustin. I'm sorry you experienced difficulties with the connection of the MK850 to your computer. The unifying receiver works up to 33 feet away, but if there are a lot of other devices in the general area it can cause some delays. The Bluetooth connection has similar responses when a lot of devices are in the area causing interference. You can always visit us at support.logi.com to see if there are other solutions listed for your products. Thanks for being a loyal Logitech customer.

    I am highly disappointed in this product. Bought it for my home office. Had it set up and connected to my work laptop and it seemed to work ok. Company upgraded my work laptop and gave me a new one and I was never able to connect either the wireless mouse or keyboard to the new work laptop or my personal laptop.

      Hi! Sorry to see you're having connectivity issues with your MK850 combo! You can try to ask your IT dept to reconnect the devices to the receiver with the Unifying Software tool. But if you have any questions, check out the Logitech support page at https://support.logi.com/hc/en-us/articles/360023300114. Continue to enjoy!

    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!!
