I will give it credit for making me think about my embouchure. What had me interested was the promised high G. I was then told by several competent teachers on this forum and in person that only practice would get me that regardless of the embouchure I used. I decided to save the $50 and just practice. The teachers were right. I too was turned off by the Quixotesque rantings on "the machine", although he has some good points, they could be said better IMO.
