Query: Harmony 550

I purchased two of these things as Christmas gifts and found them to be so difficult to set up and so unreliable that I found myself unable to give them away. Tech support was no help. Level one support went through the same things I had already done, and referred me on to level two support. Level two support sent one Email saying they couldn't get in touch with me. I had stayed home all day the day they were to contact me. I Emailed back indicating that I was there and asked that they try again. No further contact was the result. I don't think my situation was all that unique, Olevia TV, Samsung DirecTV box, Sony DVD player. Should have been easy, anything but. All in all, I would rate it a ZERO but one is as low as I can go.
