I've read this book with much expectation, it was very boring all through out the book
Solution: Negative
Why? Review writer does not like the book because it was boring, therefore it is a negative review.

New input: The thing is I like the display and everything , but the first monitor when I got had a bad pixel in the middle . So I understand it happens , return it and got another one same model . Two days later the same thing happen , and two more days I got one more bad pixel . So I am returning this one as well ,but no exchange this time . Just not worth it . Plus you can not adjust it , it stays only in one position .It may not happen anything with this bad pixels , but I don't want to take a chance . It's a hassle .
Solution:
Negative
