I was so bored the other day I actually read one of these ads, you know the ones with the tacky 80's ROK guitarist in them? It seems that this product makes a very bold statement, they guarantee that you will have seen an improvement in your ability to recognise perfect pitch within 40 days of listening to the 5 introductory CDs... and if not you can return the CDs and get your money back, no questions asked! Obvioulsy there's nothing to stop you ordering the CDs, copying them and sending them back, so I presume that the product must work so well that people are happy to pay for it after the demo period? Has anyone ever tried this product? Does it really work as well as they claim? I mean $170 or whatever is not much to pay for perfect pitch, if it actually works, surely?
