I was very unimpressed with Holosync at first, although Awakening Prologue was deeply relaxing. However, after nearly two years in the program I am very impressed. At times overwhelm has made it tough to follow the program, but I am glad I did. I do not believe that there is one product which does it for all individuals. I certainly agree with the criticisms of Centerointes advertising. In the end it is up to the individual. But if it works for so many don't be so quick to criticise.
