After Displaytod my Harmony 555 and the still good experience with this remote control I was looking for a replacement (is apparently not built that one kneels on it ...). Since I am operated with a maximum of five devices completely (the old man was a gift) was my choice due to design / price / performance on the Harmony 600. The 650 lost because of the ugly color displays acting and I do not regret my choice. Display: Top. The remote control is now on four actions with five different devices programmed. So there are keystroke either a game console, the satellite receiver or the HTPC either the projector or the TV. The runs still all about a LIGAWO HDMI Matrix, a HD PVR 2, a vicious decoder. Here at last I had to create a scheme for programming ... Switching between actions work like turning, available and all equipment not used in the follow-up action will be shut down as planned in the program. Only the programming software bothers me a little. I have to install additional software to me then to be able to log on only online to edit the programming. An offline version has not been proposed, and the charging time is quite long. Nevertheless, the whole thing is nicely arranged and served its purpose.
