The concept is interesting and quite brilliantly to control the media devices in the house / living room Central. The elaboration of this, unfortunately, has become a snapshot. Material as always with Logitech very good in design and workmanship. Device via Smartphone App: A nightmare. Very stiff and slow. Add the device is quick, however, probably because relatively new equipment. The control can be carried out very good and very good control with the keyboard. Hub can be hiding in the closet, yet everything is desired. Complex / Exotic function should be added, however, cumbersome. This whole back and forth configuration costs ultimately more time and energy than you by networking (theoretically) saves. For technical and enthusiastic users certainly a pioneering device that should be tested for normal technology consumers simply too early and stiff. Power, however, hope for more from the direction.
