It worked for me At first when the sent me an email about the product I was skeptic as well. Tried the audio anyway because they had a 90 day money back guarantee and I got products from the company before, which were pretty good. In the audio there was this man breathing throughout the whole cd, this did not work for me. So I emailed the company, telling them about my experiences with this breathing. They jumped on it and released a version without the breathing. Now these audios truly help me to get to alpha level, I combine it with the bagha or 3 to 1 method from Silva Method. It really helps me to relax and get to apha much faster.
