Power Line Pillow

Do any of you use Blue Circle's Power Line Pillow (noise hound - Model B86mkII)?

At what level would you state its effectiveness in improving the sound of an audio system based on the following scale? (I live in an apartment building which is fairly old and for the time being cannot afford a line conditioner)

1. outstandingly effective
2. very effective
3. moderately effective
4. mildly effective
5. not at all effective

Any further details would be greatly appreciated.
