I ordered this product mainly because of so many good reviews, and it is sad to tell you that it does not work like they say, in some of the circuits I have used it will make it even worse, some will have an insignificant drop in temp. and so far nothing like the results this people describe, I guess I'll have to use the exact same systems they are writting about to have those result, so far it is just as good/bad as some other cheaper products on the market, I'll keep looking!
