The so called blinks are exactly that, its like blinking through a book without reading the valuable content. The coverage of the books (some of which I have read the entire book) is at best minimal. You cant shortcut a valuable book and the pricing for just reading brief summary(s) is too much. Provide value and then charge the customers.
I am rating for the purpose of the app not the functionality.
