And here's a totally different review than the above ;)
We used the colored version, and I thought it moved slowly. We hardly ever used the games or the extra "fun" things that came with it. If I were to do it again, I would just get the teacher's manual, workbooks, and readers if that is cheaper than getting the entire package with all the other extra stuff.
We used the entire year of the K materials back when my dd was 4yo. They did not have the transition package available then.
