Useless product if USB device is Lost or becomes faulty
9 November 2018
I had purchased MK220 wireless Keyboard and Mouse. The USB device supplied along with this product, got misplaced. Now, the part is useless. It seems there is a hardware level pairing of Keyboard and Mouse with device. The USB device is also not sold separately. If you buy, Logitech wireless Mouse , then also you can not use the available other Logitech wireless Keyboard & Mouse with the USB device received with the new USB device. I also bought Logitech Unifying Receiver so that I could use the available Wireless Keyboard and Mouse, even that is also not working. It seems that it is all junk. In view of these observations, my own assessment is that the Wired Keyboard and Mouse are better options as compared to wireless ones. As a user, we expect the availability of Logitech USB device which should automatically get configured (plug and play).
