I have a Harmony Ultimate Home Touch with the Hub. Everything has worked great since day one. You need to take the time to learn how to program it. I have it controlling my FLIRC USB IR receiver attached to my HTPC (KODI), Apple TV, PS3, XBOX 360, Sony Receiver, and Sony TV. Everything is out of sight in my AV rack. Never have any kind of hiccups or communication problems through the walls. Sounds like most bad reviews are from people who dont want to take the time to learn how to setup their network or dont want to take the time to learn how to program it correctly. I like mine so much I will be adding the Z-Wave controller soon for more automation! Keep up the good work, Logitech! The possibilities are endless as to what you can do and control with this remote & App!
