I own their top of the line HT bar..the Powerbar 10. I don't think these things work at all. The lights look pretty, so my girlfriend thinks. waste of money. I tried hooking up my cablevision to it..made my reception WAY worse than direct to the TV. We see lightning maybe once a year where I live. Maybe less. i have seen lightning maybe 5 times in my 37 years. It might be doing something but i don't know for sure so that makes it a waste.
