I have one and I might ad that I paid a LOT less then the Amazon price
As I remember it was under $600
On the inside there isn't much and it probably is short of some of the filtering many of the purely filter folks have. When I first got it I did a lot of A B testing and plugging the TV into is made a huge difference in the picture. I never have had the chance to test any of the rest of the market to the Furman sorry.
I have a Gill Alana Pre Amp and a Modwright 150 SE plugged in. I did the Furman or wall socket test and the Furman was better. Not a lot but better all the way around.
My reason for the purchase was for the surge primarily as I am semi rural and with the rain and wind in Oregon winters trees can fall at any time. And actually most of our power outages are folks hitting poles
Hope this little info helps. Alan
