To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
The quality is very poor, I can't rotate this format of book not mentioning about making the font bigger! Now I am sure I'm gonna stick to a paper version of it in the future. One good thing is it didn't cost me a lot! I just wanted to read it en Español because I need to develop my language skills and also my son soon will start learning Spanish, so this is good way to help him- listen, read & write in a foreign idioma. We have all parts in English and Polish + a few Polish audiobooks, our family enjoys these books. They are really funny! I recommend them to anyone despite the age.
