I take this books for several years and unfortunately have to say that the paper and cover quality is extremely deteriorated. The paper is really incredibly thin, as have already written many other reviewers. That's nothing compared to the stapling 2 years ago. It seems, pushing on all sides by so so that the readability suffers genuine. Even the cover has become significantly softer (because too thin), but that does not make itself as a negative effect, as in the paper.
A beautiful example of how you can make a product broke, just because you want to reduce production costs. Will probably be the last time was that I ordered the books. Everything was better :)
