Every single device that is utilized for entertainment has controllers today. The problem is that each device has its own controller. Logitech Harmony 676 combines the various controllers into one. It can turn on your television, DVD player, CD player, cable, DVR and satellite controller at the same exact time. It can basically operate anything that accepts infrared signals. Unlike other universal controllers, this controller can connect to the internet and be updated. Not only does this controller control everything, a person can set it up to automatically adjust to their desired settings. Furthermore, the controller is extremely easy to setup. All a user has to do is plug the controller into the computer via USB cable, install the software provided and follow the given instructions step by step.
