The information is pretty good, but I'm very disappointed that even using the largest font, you can't even SEE the charts let alone what it says!! The font doesn't change on the charts and they look like they are very faded. I even tried using a magnifying glass and I STILL can't make out what it says. Very frustrating and disappointing. So now if I want to see what the charts say (and the charts are the key to the whole thing) I'll have to go buy the book. They should set up a place we can go to download these charts and lists after we spent $10 on a Kindle book that we can't read!! Don't waste your money on this Kindle book - go buy the book itself.
