Not sure about the material itself but the whole eBook experience has been a major inconvenience for me. I thought I would just get a PDF or Word document or something similar BUT the CBDReader is TERRIBLE to read with.
Even downloaded the App to have on my Android.....that was worse. I would gladly give it back and order the print version.
Outstanding! Bought it a few years ago. Still have it on a table next to my bed and Bible. Gives basic, generalized info with a touch of opposing views. Well worth the price!! I later bought two more as gifts - can't seem to give them up though. Selfish, just selfish!! Pray for me.
