I really needed a replacement for my old Logitech Harmony and Bluetooth should be able to. The reviews were divided here, so I tried it once. First, the app. Disaster. More I must not say. From time offset apart. How should my wife something use? At most to use for nerds. Crashed the app is me often. Is it possible to forget. The remote control ... not at all. Black buttons on a black ground without lighting? I watch movies without switched lamps. As the important keys, such as start, stop, etc. even beyond the reach are (one-hand operation not been possible for me) a NO GO. About the switching capacity I write not only here. Time it's not time. A tragedy. 6 put and urgently make improvements. I need as a remote control, but currently there is Logitech nothing works.
