All of of books I have bought from you have been great the Ebooks included. The information in your books is very easy to understand and the books are very easy to use on a day to day basis. I use my hard copy of listen to your gut every day. I would give your books and recommended supplements that you sell through your store online the highest recommendation possible. 
Going on the elemental diet with the Absorb Plus shakes has saved me from surgery (at the Mayo Clinic), twice in the last 6 months.  If I could afford to do it I would eat nothing but your shakes and supplements 100% of the time.
Keep up the great work!
