Let me tell you how shitty they were, and why they probably put this thing to the curb:

The "Receiver" part of that thing was so limited, that it basically interpreted all kinds of ultrasonic sounds as "commands". Whenever I pulled my curtains open or close, the TV went nuts. It turned off, or it turned the volume to 11, or whatever. I was working on a small piece of metal on my desk, and with every stroke it changed channels, either up or down. This thing was annoying.
