Anyone familiar with the Harmony remote controls, who knows what I write. The programming has been 900 a little simplified compared to the Harmony, as far as the station or favorites occupancy. The Ultimate my equipment switches even more reliable than my "old" Harmony 900. When it could easily happen that a device is not turned on or turned off, because the commands in quick succession came. That was by a little "fumbling" in the online programming of Harmony to fix but still it could happen that once a device unlocked in rare cases, against orders. That's never happened to me in the Ultimate. Only the ergonomics of the key assignment on the Ultimate has deteriorated in my opinion, compared with the Harmony 900. To sit the controls for DVD / BluRay or PVR (Play, FF, etc.) above, which I personally find ergonomically poor. But I can control all my devices and actions by Iphone, Ipad and Ultimate and I can without any additional hardware control a PS3 and finally the Wii and WiiU.
