Jschatz,

the book has some interesting points and seems plausible, but I havn't been able to use any of the techniques. I just don't have the patience to consistently practice what it sugests. Its all pretty much just "relax and comand your subconsious to remember".
I could see the methods lending to greatter memory usage for those capable, but for me the book was a waste of money.
I think they have a money back guarantee so you probably wont lose anything if you decide to try it, but don't be suprised if you aren't satisfied.
If you get it post the results.
