I've only been thru it once and I can say that it explains tons of things about memory and how it works BUT it does use pegs and associations along with other things. In the same way Photoreading used Speedreading techniques along with other things- this course does the same.
She gives you enough things to do with your mind that you'll never be bored again.
What I thought was interesting was that each time you did something you created another thread of your "web" which explains why someone does Photoreading for a while for 'nothing' and then WHAM, they "get it." If someone quits before they get to that point they're screwed, they get nothing out of it and they end up flaming PR on Amazon.com or something.
There are many parts of this MemOpt that SHOULD have been in Photoreading, it would have helped alot. (Hint, Hint...)
It's worth investigating. I'm not doing cartwheels over it like I was with PR though.
