The problem seems to be that the thing you're here to laud has no proper scientific basis. I am unable to assess such things, since I'm not a neuroscientist.
However, things like lack of peer-reviewed scientific journal articles, etc. etc. etc. are more compelling to me than postings from essentially anonymous supposed parents, who even if they are bona fide will have paid thousands for a treatment and will thus be psychologically invested in not feeling bilked.
As an example of how baseless claims can result in loss to the public, consider the Q-Ray bracelet, which was sold through claims of pain relief that were never substantiated:
http://en.wikipedia.org/wiki/Q-Ray So no, it's not wise to just take advertising claims on faith, least of all faith from people who may be suffering from the placebo effect.
Let's say, hypothetically, that a Brain Balance salesperson decides to create an anonymous account on a website to sell the product, and he picks a website where lots of people with autistic-spectrum children go. Of course that salesperson will say positive things about the product, ignore the fact that it goes against or is not founded on any established science, ignore the fact that it's created by a chiropractor, make claims based on testimonials from parents of the "cured" without any proper corroboration, say that there is no proof that it doesn't work, etc. Such tactics have already been handily debunked previously in this thread.
Like no5no5, lots of red flags go up for me when I see lots of buzzwords accompanied by little or anything of substance, and lots of money spent on what sounds like basic academic drills, not left-brain/right-brain retraining.
If you're not a Brain Balance salesperson, you'd make a fine one.
Your post is indistinguishable, to me, from spam posts selling products that pop up on websites fairly often, and I think that's what some others are seeing. I apologize if you really are a parent questing after answers who has simply bought into the buzz about this product.
