I got it and used it. I havent taken boards yet but I will say that after using it I made some 'connections' that I might not have otherwise. Even after reading through FA. It is by no means all inclusive, but is high yield material most likely to be seen on the test.
Cons: He goes painfully slow at times. Occasionally makes a mistake, and if your following in pen your page of notes looks like crap.
Overall, I am glad I got it early on but it wont be a key board prep tool. Since I have the book filled out, I plan to read it (~250) pages of notes which can be read quickly during the last few days prior to the test + Saverese.
