The answer is easy.
Those that like to waste their money on expensive un-industrial/ un-scientifically proven trinkets like fuses and goo are welcome to waste their money. But DON'T pollute the Audiophile forums trying to sell the stuff to others until the items can and are proven REPEATEDLY by scientific testing to do what is professed they do.
Those who don't believe in them, ignore the subject and save your money. Let the believers run around, drink red cordial and say obviously silly things they cannot prove.
