I have one. It’s sitting over there on the shelf. I could not detect any changes in my system while using it so I removed it. Sell it to you for cheap if you want to try it for yourself.....

@gnoworyta - if I were you, I’d spend the money on a Puron. You will hear a major improvement in SQ. There is a post Puron thread here. I recommend reading it. 

Thanks for all the responses thus far...

I use 2 myself and love what they do.
