Any opinions on Grammar Ace from Sonlight?

I tend to follow the Bluedorn's method and put off grammar till around age 10. I was wanting opinions on this program or suggestions on another program that assumes no knowledge of grammar to begin. Any suggestions?

I have it but have not used it. It looks straight forward and not difficult. It comes with a great School House Rock CD we have played a good bit. Another grammar program I love is Growing with Grammar. Many also like Rod and Staff or use grammar which is built into a writing program like Classical Writing.
