As the old saying goes, "If something seems to be too good to be true, it probably is". I try to keep that in mind while examining tweak products. And I also have doubt if their explanation has no basis in science. Many products have dubious "owner's reviews" of their greatness, and offer no reason why it works. Then there are things that do work, and better ones do cost more. Until suddenly the price has just gone stratospheric, in those cases I am reminded that a Timex is a very accurate time piece, but a Rolex cost 1000 times more, and doesn't keep time as well. But, it's a status symbol and is real pretty to look at. No one argues that the Rolex isn't a good clock. Back in 1986 I bought a Monster record clamp, it was $35, I had my doubts but I bought it! And it worked! Nothing revolutionary but it did help tighten up the bass. Last year I see the exact same record clamp, I mean exactly the same, selling for $300. Has inflation gone up that much since 1986? If so I really need a cost of living increase!
