I don’t. I don’t think I’d go applying undampened vibrations to a foetus with a delicate, semi-developed aural system based on the opinions of some pregnant moms. To me that would very much fall into the category of ‘woo’.
Wouldn’t you prefer to see some sort of longitudinal study of the developmental outcomes of children who were exposed to such a practise before you crammed one of those kajiggers up your own hypothetical babymaker?
But for all the cool diagrams, I’m pretty sure there is no such study. Make no mistake, this product doesn’t exist because scientific endeavour has proven (or even suggested) its merit, it exists because some dick who wants to make money thought it sounds sciencey enough to turn over a few units. It is woo.
