I am sure more people can add to this, but I was very impressed with URC when my MX 500 would not work my new TV. I called them up and they said send it in. I did and they added three new devices to the MX 500 so that I could work all of my new components. They did this free of charge and paid for the return shipping. They also provided instructions/information on the new firmware that was added. Yes, I don't like the new policy, but I buy from AD's so it isn't as much of an issue to me. In addition I also have an MX 800.
