I love this product, and here are the reasons: 1) the scripture text are hyper link to your Bible of choice. 2) It is easy to navigate by clicking to the table of contents tab. I can see the entire book (volumes) on one side and the selected items on the other. 3) I love the prayers and it is great to have it in an electronic format. Overall I think it is easy to navigate without all the interface items discussed in prior comments. Once you fall in love with the prayers, the small navigation items seem like a small sacrifice.

How many hours of video?

I love it! It helps me with my prayers.
