Title: It really does improve the way things work!
Review: I have a middle price range audio system and a friend told me that I should include a power conditioner as part of the system because I have rather dirty power coming out of my sockets and it caused a slightly audible hum. I couldn't afford to spend the $3... for a real conditioner so I bought this thing hoping that it would do something in terms of quieting down the electricity. I was stunned that I couldn't hear anything but my stereo after that. Good deal.
