I'm sure they work well. Belkin has been doing this for a long time. Personally I like the Powervar and Oneac commercial grade line conditioners. Not as pretty but very effect, I feel safe knowing that some of my gear is plugged into one. I do also use an inexpensive Tripp Lite for some gear that I don't care about as much, think it cost about 70 bucks.
Where's this conditioner on the net you are referring to?
