I can't speak to 100 easy lessons, but I have used PP with 2 children (one already reading to fill in gaps and one from ground up). I like that it is not distracting, although for one of my children I have to cover up some text on the page to focus him in as there tends to be a lot of words on a page. I am about to teach my 4 year old how to read after he gets a couple last basic sounds and I will be using PP. I also supplement with Bob books, A Beka K readers and any other phonics readers I can find.
