Review on Enhanced Wireless Keyboard and Mouse Combo - Logitech MK540 by Aditya ᠌

The kit's primary flaw (although there are actually two of them) is that the keyboard and mouse fall off the bluetooth, or only one of them works, or the mouse works but shuts off at the worst possible time. The button may not always be depressed. The keyboard is the same. Despite being less expensive, my Logitech K400 Plus has worked without a hitch.
