Input: I bought the book on kindle, this was my mistake. The print is so light that at times it causes a strain to read. Not really great but definitely not horrible. But you may think differently. Sorry for that. By the way, I would advise the author make some changes in future editions. Maybe have more pages with larger text, better pictures. Even an updated picture of each of his main models. There are two pictures per page. Of course it depends where or when you want your photos.
Output:
Bad review
