I love it. Put together great and easy to use and follow. What I like best of all is it's not packed full of information you don't nee. The quick sheets are amazing ,information at your finger tips.
I gave it a 4 only because I haven't been able to dig deeper into the book yet. I will say I was able to use the book to answer a patient's question for her insurance so the day after I got it I was able to utilize it! Right now I would say so far so good!
