from Dailytech.com: Oklahoma Narcotics Bureau claims sound is dangerous to kids

I think the enormous price tag puts more emphasis on that they wouldn't ask such an preposterous amount of money if it didn't work, to make it more believable. But to be honest, things like that are only worth pirating.

Again, whether you agree with their pricing or not, endorsing pirating - especially when pirating directly affects me and my livelihood - is not appreciated here. Please respect copyright and intellectual property, mine and that of others.

Just because it didn't work for you, doesn't mean it won't work for someone else. They could not sell it at that price if it was not effective for most people. I am not sure what brainwave entrainment technique they're using, but I do know that some people can resist brainwave entrainment, and some circumstances cause it to fail partially or completely.
