The biggest drawback is the device which is not possible without a computer with an active Internet connection. A forced account at Logitech is also necessary.
Man can really change everything, when you have mastered the software.
All users without Comutererfahrung and with many devices I can not recommend this remote control directly.
The following devices do I control it:
TV: Samsung LE27
SAT: Topfield PVR 5000
Media Center: HDX 1000
Receiver Sony STR-475DE
DVD Player: Medion MD81290
