"Memorize in Minutes" for Teaching Multiplication?

Any thoughts on Memorize in Minutes by Krimsten Publishing?

I'm reading about this method now, which uses pictures and rhymes to help children memorize multiplication facts and really feeling tempted to give it a try. My 9 year old son is on the autism spectrum which may or may not explain his challenges with certain types of memorization, but this really seems like something he might take to. Especially given he has such a silly side, and given that many autistic kids do marvelously well with picture stories, when being taught social and real life learning skills. Maybe pictures and rhymes could teach math too?

My son still cannot tie his shoes, ride a bike without training wheels, and has a horrible time with math. Such that, he's decided he hates the subject inside and out. This is a problem. He doesn't let me instruct him in this subject because he can't stand to "not get it". Does that make sense? If something doesn't make sense to him, he avoids it. This same kid is testing at the 8th grade reading level and received a 97% on his state reading assessment. He's smart, but he's fighting against a disability which affects his ability to inference and sometimes focus. He's also suffering from an anxiety disorder which means when he faces a challenge, we often find him overwhelmed in tears and sometimes rage, which isn't exactly conducive to learning. 

So, I wonder if anyone has any experience with "Memorize in Minutes" and if so what that experience has been? I'm 95% sure I'm going to purchase this and if/when I do, I'll let you know how things go. If it does work with a special needs child, it would probably work for others... even those not on the spectrum.

I'm trying to decide if I should just order the student download or if I need the entire program which is sent via snail mail and includes a teacher's manual, flashcards, quizzes, and lesson plans. The high point is the program is on sale for $20. Hard to imagine how I could go wrong at that price! lol  I'll let you know what I decide!
