Hi Grant,
I have their "Easy Enhanced Learning" CD and I like it quite a bit. They have 2 different people speaking instead of just one and have some music or sound effects to enhance what they are saying.
It is a little bit hard to say exactly how much it has helped after using "Personal Genius," "Memory Supercharger" and the other LSC products I do seem to be processing and integrating information better than before.
They don't seem to make quite as sharp a distinction between left and right sides. Both sides are heavily metaphoric.
My personal suggestion would be if LSC has something similar, get it first, use it a bit and then get the Changeworks product for a slightly different "spin."
Mike
