If a stranger set a bowl of soup in front of you and said "Eat it -- it's good," you're probably not going to simply trust what they said,unless you're stupid.
Sti-Co products tend to be extremely expensive comparatively, and if you look at the spec-sheets, tend to be broad-band & thus little to no-gain. It's always amusing to hear their marketing people promote their products, then talk to one of the engineers about actual specs, then get the price.
