But Jack....

WHO gets to draw the line in the sand between what "works" and what's a "gimmick"? If we used the logic from your thread......why even wash your clothes in neutral detergent......or avoid smoking on stand? Where's that line?

I spend about $15/season on e3 and another $12/season on DDW detergent.

If it covers up 1% (though I and millions of others think it's doing a lot more)more than NOT using it.....then that line you're talking about is a financial one that some just don't wanna cross.
