ProCombo-4 is arguably the sleekest and most beautiful keyboard and mouse combo. It is completely wireless, so you do not have to worry about the limitations wired keyboards and mice bring. Simply plug in the Nano USB and start using it. The keyboard has very soft keys which allows the user to type without the annoying key press sounds. It is designed with such elegance and practicality that it offers wrist rest panel at the bottom for easy and fast typing. The mouse has all the functions and shortcuts that you require while using your computer. The Auto-Sleep function puts the keyboard and mouse combo to sleep when not in use to save up on the battery. With a simple click, you can wake up the combo and continue using it.
