Remote delivered very quickly by Amazon, as usual. It seems quite sturdy, it took me a little time to adapt to the myharmony.com site that is the only way to program it, but once you understand the philosophy of the site, it is a pleasure. My main camera is a multimedia box that also serves as a decoder tnt, it was immediately recognized and associated with the button "TV", while it is not common hardware (Dvico TViX S1 Duo, also purchased from Amazon). The standard remote control Harmony 300 buttons are rather better placed than on the original remote, and there are some non standard keys that I could associate with specific commands of my box (choose the audio track, jump to a specific position in a video, manipulate the file system). I really do not expect much! The Tvix housing is connected to a TV, of course, and a hi-fi amplifier, I could specify that setting the volume keys affect the amp (and not the TViX unit or on the TV ). Brief for less than 30 I really replaced three remote controls with one, total satisfaction.
