Query: Disappointed

I was very disappointed with this product. One of the ports stopped working shortly after I hooked it up, and then I ended up with intermittent audio signals from the other ports. My blue ray player had intermittent audio, and when I ran the optical cable directly to the device and not through the switch, not problem. Ditto with my Dish receiver. Great idea that just didn't work for me.
