The book explains the subjects really well and has a lot of practice problems, however the explanations for the answers to practice problems don't lend much help, they are very wordy and unclear.

Wow, this thing is garbage. We have this model at the office and I was excited to bring in my coffees (k-cups that work perfectly fine in my home Keurig) and find they are not compatible in this new "smart machine". Utter rubbish.

First book I've read by this author . Well written CIA thriller. Characters seemed real but flawed. Action & humor. Hope this is the beginning of a series. Would make a great movie.

I have only been using this for about 1 1/2 weeks. My hair feels fuller, very little shedding after showers and my hair is incredibly soft! Not changing shampoo again....as long as the formula doesn't change!

Brilliant explanation of the the reasons behind the Trump phenomenon - insightful, concise and well written. (I'm 39% through the book now and will update or replace this review when I complete the book).
