    The mouse will not work on a normal desk suface. You have to a mouse pad with it and not a fan of that style of mouse.

    The mouse works off and on. Even after replacing the battery it still isn't working properly. Had to switch out the mouse for another mouse. Really annoying.

    I’ve never seen a more complicated keyboard and mouse setup! No instructions, just pictures. Worked on trying to set this up for three days and finally gave up. I returned it for a refund.

      Hi Pcentral. I'm sorry that you were unable to connect the keyboard. The MK850 comes with a Unifying adapter that you could have plugged into a computer or laptop. If you were trying to use the Bluetooth connection on the keyboard you would need to press and old the 1-2-3 buttons until the light starts flashing fast. This indicates that keyboard is in pairing mode and you would be able to find it in the settings on your device to connect via Bluetooth. If you have questions about the MK850 or other Logitech products please visit us at support.logi.com

      Hello Tomd, I apologize for the issues you're having with the Bluetooth connectivity of your MK850. Bluetooth can sometimes cut in and out if there are too many obstructions between your computer and your device, so I would suggest trying to minimize those, as well as trying to minimize the number of nearby Bluetooth sources such as speakers or headphones.

    I purchased on 1/4/20 and on 3/30/20 the 0 (zero) key on the ten key numbers no longer works. Best Buy’s says it is no longer returnable after two weeks. $110 key boards that last less than 90 days is a rip off. Stay away from these!

    Many of the keys are really hard to press and make lot of noise (specially space bar is really hard, which is used most). I was expecting really smooth keys and no noise at all for such a premium price.

      Hi Amit, sorry to see you were unsatisfied with the MK850 Combo. You do have many choices from Logitech that can fit your needs better such as the MX Keys! You also have a 1 year limited warranty with the purchase of the product that can be claimed for a replacement. But if you have any questions, check out the Logitech support page at https://support.logi.com/hc/en-us/articles/360025071293-Warranty-MK850-Performance. Hope that helps!

      Hi JazzBlueRT,
      I am sorry about your bad experience with your Logitech keyboard, and I assure you that this is not a common thing to happen. I suspect that the glue that keeps the rubber base attached to the keyboard became loose due to temperature changes during shipping or storage. For the same reason, Logitech offers a 1-Year Limited Hardware Warranty for your keyboard. Getting a replacement should not be complicated if you go through the proper channels. Feel free to reach out to our support team to get your replacement without hassle at https://support.logi.com/hc/en-us/requests/new?ticket_form_id=360000621393&mID=12746 - Leo from Logitech
