    Keypad shut down and never tun on after 1 week of use. Changing batteries did not help as well. This was the second purchase, but ended up with a crap item. Mouse function at 90%.

    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

      Hi! Sorry to see you're having connectivity issues with your MK850 combo! You can always use another mouse that uses the Unifying receiver instead of the one that came with the combo. 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!
