I used it, but didn't pay for it; I beta tested. I did not get more information than I'd gotten from Ruf's book, and in fact, I feel that I got less.

As I said before, I used Ruf's levels to persuade DH that DD has unusual abilities. Since he has little experience with NT kids, he believed that DD was typical, despite her level 4/5 milestones. (I think he still has trouble understanding how advanced she is, but at least he's convinced that she's gifted.) As a list of milestones, I found it to be a helpful, if extremely limited, piece of information. As an online test, I found it to be pretty ridiculous. smile
