I watched one of their promo videos and it was a bit of a turn off (but that doesn't mean they don't have a good method... for some students). It put me off because they were lying within the first 20 minutes. Piano in almost every other form is taught the same way as it was in Mozart's time, they stated. Come on. Do they think we aren't not going to notice how ridiculous that statement is? There's the Taubman method, Suzuki method, Alfred method, etc., etc., etc.
I taught myself when I was around 6 with a book one of my Aunts gave us, via a diagram that mapped the keys of the keyboard to the grand staff. That was it until my mid 20s.
I maintain that no one method is going to work for every one and the best approach is tailor made.
